Protein Data Bank (PDB)

• The Protein Data Bank (PDB) : a repository for the three-dimensional structural data of large biological molecules, such as proteins and nucleic acids.

•  The data, typically obtained by X-ray crystallography or NMR spectroscopy and submitted by biologists andbiochemists from around the world.

• The PDB is overseen by an organization called the Worldwide Protein Data Bank, wwPDB.

Examples Of Protein:

LIPASE

NEPRILYSIN

HTPX

LONA

PROLYL

LEXA

Description of Protein:

LIPASE	The binding of Thermomyces lanuginosa lipase and its mutants [TLL(S146A), TLL(W89L), TLL(W117F, W221H, W260H)] to the mixed micelles of cis-parinaric acid/sodium taurodeoxycholate at pH 5.0 led to the quenching of the intrinsic tryptophan fluorescence emission (300-380 nm) and to a simultaneous increase in the cis-parinaric acid fluorescence emission (380-500 nm).
NEPRILYSIN	Neutral endopeptidase (NEP) is the major enzyme involved in the metabolic inactivation of a number of bioactive peptides including the enkephalins, substance P, endothelin, bradykinin and atrial natriuretic factor.
HTPX	is an enzyme that catalyzes the hydrolysis of a chemical bond. For example, an enzyme that catalyzed the following reaction is a hydrolase:
LONA	Lon ATP-dependent proteases are key components of the protein quality control systems of bacterial cells and eukaryotic organelles. Eubacterial Lon proteases contain an N-terminal domain, an ATPase domain, and a protease domain, all in one polypeptide chain.
PROLYL	The solution structure of the periplasmic cyclophilin type cis-trans peptidyl-prolyl isomerase from Escherichia coli (167 residues, MW > 18.200) has been determined using multidimensional heteronuclear NMR spectroscopy and distance geometry calculations.
LEXA	LexA repressor undergoes a self-cleavage reaction. In vivo, this reaction requires an activated form of RecA, but it occurs spontaneously in vitro at high pH.

IP ADRESS

• An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. 
• An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there."
•  The designers of the Internet Protocol defined an IP address as a 32-bit number[1] and this system, known as Internet Protocol Version 4 (IPv4), is still in use today. 
• However, due to the enormous growth of the Internet and the predicted depletion of available addresses, a new version of IP (IPv6), using 128 bits for the address, was developed in 1995.
• IPv6 was standardized as RFC 2460 in 1998, and its deployment has been ongoing since the mid-2000s. 
•  IP addresses are binary numbers, but they are usually stored in text files and displayed in human-readable notations, such as 172.16.254.1 (for IPv4), and 2001:db8:0:1234:0:567:8:1 (for IPv6). The Internet Assigned Numbers Authority (IANA) manages the IP address space allocations globally and delegates five regional Internet registries (RIRs) to allocate IP address blocks to local Internet registries (Internet service providers) and other entities.

These are the difference between TCP and IP:

TCP	IP
ensures the reliability of data transmission across Internet connected networks	dictates how packets of information are sent out over networks
checks packets for errors and submits requests for re-transmissions if errors are found.	lets any computer on the Internet forward a packet to another computer that is a step (or more) closer to the packet's recipient.

XML XML XML

• XML stands for eXtensible Markup Language.   

• XML is designed to transport and store data.

• XML is important to know, and very easy to learn.

  DIFFERENCE BETWEEN XML AND HTML:

  XML	HTML
  To transport and store data	To display data
  Focus on what data is	Focus on how data looks

Key terminology:-The material in this section is based on the XML Specification. This is not an exhaustive list of all the constructs that appear in XML; it provides an introduction to the key constructs most often encountered in day-to-day use.
Example:


      Tag
A markup construct that begins with < and ends with >. Tags come in three flavors:
• start-tags; for example: <section>
• end-tags; for example: </section>
• empty-element tags; for example: <line-break />
XML declaration
XML documents may begin by declaring some information about themselves, as in the following example:
<?xml version="1.0" encoding="UTF-8"?>

WHAT?

HTML stands for Hyper-text Mark-Up Language. HTML or Hyper-text Mark-up Language is a globally accepted programming language for formatting web pages. In today's world, it is commonly used along with JavaScript and Cascading Style Sheets (CSS) to give web pages the look and feel we desire. Through HTML, the look and appearance of images, links, headings, text, page layout and just about every element of a web page can be formatted. While there are other globally-recognized web programming languages and tools like content management systems today, HTML continues to be the predominant programming language for creating web pages. It is also the most optimal for most small and growing businesses that do not really need advanced functionality on their website. Below are some of the advantages of using HTML while creating your website.

We learned how to make a table by using simple html code and how to insert a non-moving picture and moving picture. 

INPUT TYPES OF HTML:

INPUT TYPE	EXAMPLE	CODING
COLOUR	Select your favorite color:	<#input type="color" name="favcolor">
DATE	Birthday:	<#input type="date" name="bday">
E-mail		<#input type="email" name="email">
Month	Birthday (month and year):	<#input type="month" name="bdaymonth">
Number	Quantity (between 1 and 5):	<#input type="number" name="quantity" min="1" max="5">

**NOTE : delete the '#' beside 'input' if you want the coding to appear on screen**

*MAPLEMAPLEMAPLE*

We are from Computational Theoritical Science students. CTS for short form. Our names are Azalea Amirah bt Muzamir, Nur Liyana bt Ab Ghani and Sharifah Najibah bt Syed Hassan. this is our first semester in IIUM, we have to attend Computer in Science as one of our Kuliyyah requirement.

Our first topic in this course is Maple. Maple is a system for doing mathematics on a computer. Maple combines symbolic manipulation numerical mathematics outstanding graphic and sophisticated programming language. We will use this program later on when we are working. This will make our work easier.

These are the examples of symbols that can be used in Maple.

NO.	OPERATION	SYMBOL
1.	MULTIPLY	*
2.	DIVIDE	/
3.	POWER	^
4.	SQUARE ROOT	sqrt
5.	COSINE	cos
6.	DIFFERENTIATE	diff
7.	EVALUATE	evalf
8.	COMMAND	#
