Question

ExPASY contains a number of programs to determine posttranslational modifications based on MS molecular mass data.

(a) True

(b) False

I had been asked this question during an interview for a job.

The above asked question is from Post translational Modification in chapter Functional Genomics & Proteomics of Bioinformatics

Answer 1

Right option is (a) True

For explanation I would say: Find Mod is a subprogram that uses experimentally determined peptide fingerprint information to compare the masses of the peptide fragments with those of theoretical peptides. If a difference is found, it predicts a particular type of modification basedona set of predefined rules. It can predict twenty-eight types of modifications, including methylation, phosphorylation, lipidation, and sulfation.
