Publisher's Description: |
This program integrates common functions biochemists perform on a daily bases. In addition to conventional sequence input protocol, the program offers a new protocol of entering sequence by its building blocks and corresponding counts. This facilitates the possibility for the program to deal with very complicate, branched, cyclic and lengthy sequences. The program also extents its applicable range to general organic chemistry with its user definable fragment database.
Module Description
AAA Amino Acid Analysis: This module calculates optimized residue ratio for amino acid analysis result. By entering residues easy to be oxidized in hydrolysis into Residues Not To Be Optimized section its influence to the optimizatin result can be minimized.
BBC Building Block Composition: This module discerns identity of unexpected product based on the fact that building blocks: amino acids, fragments, possess discrete weight values. Upon scanning their combinations, the ones with least deviations will more likely be the derivatized product.
Digest Digestion Pattern: This module predicts digestion products through user defined enzymatic or chemical pattern.
E A Elemental Analysis: This module calculates the theoretical percentage of different elements in a sequence. By further entering experimental percent composition for each element, its empirical formula and/or its aggregates can be identified.
Frag Fragmentation: This module predicts fragments generated in mass spectrometor by three types of bond cleavage: CH/CO, CO/NH, and NH/CH. The resultant fragments can be directly imported into Mass module for a simulated mass distribution pattern.
Helix Helix Wheel/Net: This module displays and manipulates sequence wheel/net presentation of helix structure.
Iso Isotopic Profile: This module predicts isotopic profile of a input formula or sequence, in either + or - mode with charges varying from 1 to 3
Lib Combinatorial Library: This module predicts mass spectra for combinatorial libraries, such as peptide libraries, in either + or - mode with charges varying from 1 to 3. No mass round-up is performed until last step to assure accuracy. What is more, the module extends its prediction power to organic libraries: The random variants could be either amino acids, fragments or both. The result also includes random section residue combinations
Motif Motif Discovery: This module predicts potential drug active sites in sequences via pattern recognition. It facilitates the scanning of pre-set patterns or random repeating patterns, potential pharmacophores, among loaded sequences that demonstrate same biological activity.
M W Molecular Weight: This module calculates molecular weight of peptides and proteins. The input could be performed either through conventional sequence protocol, or with building blocks such as amino acids and fragments. The alternative enables the module to calculate molecular weight of complicate molecules such as peptide with protection groups, peptido mimetics, lengthy and branchy molecules, etc. Further use of atomic weights generally extends the module's power to calculate molecular weight of any compound.
Auxiliary Description
Database Database Management: This auxiliary module allows user to manage all databases utilized in this program, such as amino acid database, fragment add-on database ... etc. The open design allows user to customize databases according to their specific project.
Sequence Sequence Loader: This auxiliary module allows user to load and parse sequence into the entry section of a corresponding module. The expert system automatically recognizes properties such as side chains, cyclic structures, pseudo replacements and additional adducts.
Code 3 < > 1 Code Base Switch: This auxiliary module allows user to automatically toggle between three letter code and one letter code for all the entry fields.
