is.at: Check Residue a Fixed Position

In jcaledo/ptm_0.1.1: Analyses of Protein Post-Translational Modifications

Description

Checks if a given amino acid is at a given position.

Usage

is.at(at, target, aa = 'M', uniprot = TRUE)

Arguments

at	the position in the primary structure of the protein.
target	a character string specifying the UniProt ID of the protein of interest or, alternatively, the sequence of that protein.
aa	the amino acid of interst.
uniprot	logical, if TRUE the argument 'target' shoud be an ID.

Details

Please, note that when uniprot is set to FALSE, target can be the string returned by a suitable function, such as get.seq or other.

Value

Returns a boolean. Either the residue is present at that position or not.
