molweight - Calculate molecular weight of amino acid sequence

Syntax

molweight(SeqAA)

Arguments

SeqAA

Amino acid sequence. Enter a character string or a vector of integers from the tableAmino 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

Retrieve an amino acid sequence from the NCBI GenPept database.
```
rhodopsin = getgenpept('NP_000530');
```

Calculate the molecular weight of the sequence.

rhodopsinMW = molweight(rhodopsin)

rhodopsinMW =

  3.8892e+004
