GPMAW 8.0 (蛋白质质谱与序列分析软件)
GPMAW是General Protein/Mass Analysis for Windows的缩写，蛋白质质谱与序列分析软件。主要用于蛋白与多肽的质谱分析，也具有其他蛋白序列分析功能，如比对、二级结构分析等等。
GPMAW - General Protein/Mass Analysis for Windows
The GPMAW program is primarily intended as a tool for mass spectrometric analysis of proteins and peptides. However, a number of other bioinformatics tools have been included, so the use of the program extends far beyond simple mass analysis.
Sequence handling: Import of sequences from a number of different formats with direct database search in Entrez and in local databases (FastA format and Swiss-Prot). Sequences can be saved in local files (databases) for future reference.
From the sequence window a large number of actions can be performed. Sequences can be exported in FastA format (either singly or all sequences at once) for easy transfer to other programs.
Mass analysis: The protein can be cleaved by automatic methods (e.g. a flexible nomenclature for defining enzyme actions) or manually. The peptides are displayed with a number of parameters (various mass values - mono, ave, charges - Bull&Breese index, HPLC index, pI, charge) and can be further worked upon (e.g. cross-linked, new cleavage).
Peptide mass searches can be performed on any local database in FastA format.
Bioinformatics: A number of graphs can be displayed, hydrophobicity, dot-plot, secondary structure prediction. BLAST searches can be performed on local databases. Multiple alignment using ClustalW.
