Syntax

molweight(SeqAA)


Arguments

SeqAA

Amino acid sequence. Enter a character vector, string, or a vector of integers from the table Amino Acid Lookup. Examples: 'ARN', [1 2 3]. You can also enter a structure with the field Sequence.

Description

molweight(SeqAA) calculates the molecular weight for the amino acid sequence SeqAA.

Examples

1. Retrieve an amino acid sequence from the NCBI GenPept database.

   rhodopsin = getgenpept('NP_000530');

2. Calculate the molecular weight of the sequence.

   rhodopsinMW = molweight(rhodopsin)
   
   rhodopsinMW =
