| Comments | Annotated as alanine racemase, but could use other substrates in some organisms. In addition, it is not possible to automatically make a distinction between alr and dadX (or dadB) genes, but if these two genes are found in a genome, note that the catabolic alanine racemase dadX (which only exists in several species) is part of the dad operon (i.e. must be close to dadA gene). |
