What does Expasy stand for?
Expert Protein Analysis System
Expasy was created in August 1993. Originally, it was called ExPASy (Expert Protein Analysis System) and acted as a proteomics server to analyze protein sequences and structures and two-dimensional gel electrophoresis (2-D Page electrophoresis).
What is Expasy write any two useful Programmes?
It is an extensible and integrative portal which provides access to over 160 databases and software tools, developed by SIB Groups and supporting a range of life science and clinical research domains, from genomics, proteomics and structural biology, to evolution and phylogeny, systems biology and medical chemistry.
What is Expasy ProtParam?
ProtParam (References / Documentation) is a tool which allows the computation of various physical and chemical parameters for a given protein stored in Swiss-Prot or TrEMBL or for a user entered protein sequence.
What is the importance of sequence alignment?
Sequence alignment is a way of arranging protein (or DNA) sequences to identify regions of similarity that may be a consequence of evolutionary relationships between the sequences.
What is Prosite in bioinformatics?
The PROSITE database consists of a large collection of biologically meaningful signatures that are described as patterns or profiles. Each signature is linked to a documentation that provides useful biological information on the protein family, domain or functional site identified by the signature.
What is alignment in molecular biology?
Sequence alignment is a way of arranging protein (or DNA) sequences to identify regions of similarity that may be a consequence of evolutionary relationships between the sequences. From: Encyclopedia of Bioinformatics and Computational Biology, 2019.
How does protParam predict molecular weight?
In protParam, the molecular weight of protein is calculated by the addition of average isotopic masses of amino acids in the provided protein and the average isotopic mass of one water molecule.
What is the difference between Cath and SCOP?
These domains are classified in a hierarchical manner: SCOP sorts protein domains into classes, folds, superfamilies and families while the four major levels of CATH are class, architecture, topology and homologous superfamily.
What is clustalo a sequence alignment?
A sequence alignment, produced by ClustalO, of mammalian histone proteins. Sequences are the amino acids for residues 120-180 of the proteins.
What is unsourced material in a sequence alignment?
Unsourced material may be challenged and removed. In bioinformatics, a sequence alignment is a way of arranging the sequences of DNA, RNA, or protein to identify regions of similarity that may be a consequence of functional, structural, or evolutionary relationships between the sequences.
What is a histone sequence alignment?
A sequence alignment, produced by ClustalO, of mammalian histone proteins. Sequences are the amino acids for residues 120-180 of the proteins. Residues that are conserved across all sequences are highlighted in grey.
What is an aligned sequence?
Aligned sequences of nucleotide or amino acid residues are typically represented as rows within a matrix. Gaps are inserted between the residues so that identical or similar characters are aligned in successive columns.
