SAS is a tool for applying structural information to a given protein sequence. It uses FASTA to scan a given protein sequence against all the proteins of known 3D structure in the Protein Data Bank (PDB). The resultant multiple alignment can be coloured according to different structural features and the matching 3D structures can be superimposed and viewed in RasMol.
XDrawChem is a two-dimensional molecule drawing program. It is similar in functionality to other molecule drawing programs such as ChemDraw (TM, CambridgeSoft). It can read and write MDL Molfiles, and read ChemDraw text and binary files, to allow sharing between XDrawChem and other chemistry applications, and it can create images in popular formats like PNG and EPS.
This is FTProd, a plugin for VMD designed to characterize and identify cross-structural ‘hot spots’ in proteins. The program FTMAP identifies these druggable hot spots by docking a series of small molecular probes onto the protein surfaces. FTProd combines these output structures, clusters them, and displays them visually for easy comparison.
Amino Acid Tutor is a great tool to learn amino acid structures and codes (single letter abbreviations). You will get different types of questions, so the learning process will not be boring.
GenRGenS is a software dedicated to random generation of genomics sequences that supports several classes of models, including Markov chains, HMM, context-free grammars, PROSITE patterns and more.
SBSPKS is a webserver for carrying out sequence and structure based analysis of Polyketide Synthases, an important family of multifunctional megasynthases involved in the biosynthesis of a variety of pharmaceutically important secondary metabolites. The knowledge base for development of SBSPKS is derived from a comprehensive bioinformatics analysis of the sequence and structural features of a large number of experimentally characterized PKS gene clusters having known metabolic products and recently available crystal structures of PKS and FAS proteins.The interfaces for carrying out various tasks by SBSPKS are organized as three major functional units, namely NRPS_PKS, Model_3D_PKS and Dock_Dom_Anal .
FCP is a publicly accessible web tool dedicated to analysing the current state and trends on the population of available structures along the classification schemes of enzymes (specially kinases and proteases), G protein-coupled receptors, nuclear receptors and transporters/channels, offering both graphical and quantitative data on the degree of functional coverage in that portion of the proteome by existing structures, as well as on the bias observed in the distribution of those structures among proteins.
