Aspartate ammonia-lyase

UniProtKB accession:  Q9LCC6

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the reversible conversion of L-aspartate to fumarate and ammonia (PubMed:10334861, PubMed:10712618, PubMed:18844200, PubMed:19490103). Is highly specific for L-aspartate in the deamination reaction, and cannot use alternative substrates such as D-aspartic acid, alpha-methyl-DL-aspartic acid, beta-methyl-DL-aspartic acid or L-glutamate (PubMed:18844200). In the reverse reaction, alternative nucleophiles (such as hydroxylamine, hydrazine, methoxylamine and methylamine) can replace ammonia in vitro, leading to the formation of N-substituted aspartic acid derivatives (PubMed:18844200).
