Codon usage

Description

aminoacyl is a list containing the codon counts of 36 genes encoding yeast aminoacyl-tRNA-synthetase(S.Cerevisiae).

Usage

data(aminoacyl)

Format

aminoacyl is a list containing the 5 following objects:

genes

is a vector giving the gene names.

localisation

is a vector giving the cellular localisation of the proteins (M = mitochondrial, C = cytoplasmic, I = indetermined, CI = cyto and mito).

codon

is a vector containing the 64 triplets.

AA

is a factor giving the amino acid names for each codon.

usage.codon

is a dataframe containing the codon counts for each gene.
