Definition

D-amino acids are α-amino acids that have the R configuration at their α-carbon atom, with the exception of cysteine, which is of the L configuration. D-amino acids are produced by enzymatic post-translational modification of the isomeric L-amino acids which are ribosomally encoded. D-amino acids are found in some bacterial cell walls as well as in the some fungal antibiotic peptides.
