Diaminopropionate ammonia-lyase

UniProtKB accession:  P40817

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the alpha,beta-elimination reaction of both L- and D-alpha,beta-diaminopropionate (DAP) to form pyruvate and ammonia. In vitro L- and D-isomers of serine are also degraded, though slowly; it is the only serine dehydratase which can eliminate an amino group at the beta-carbon position. In vivo L-, D- and a mixure of DL-DAP allow growth. DL-DAP is toxic in the absence of this enzyme, it may inhibit enzymes involved in the synthesis of pyruvate and aspartate, as well as amino acids derived from them.
