-''threo''-3-Methylaspartate is an unusual
amino acid formed by
glutamate mutase and can be metabolised by
methylaspartate ammonia-lyase
The enzyme methylaspartate ammonia-lyase (EC 4.3.1.2) catalyzes the chemical reaction
:L-''threo''-3-methylaspartate \rightleftharpoons mesaconate + NH3
This enzyme belongs to the family of lyases, specifically ammonia lyases, which cleave carbo ...
. It is found in the structures of the antibiotics
friulimicin and
vicenistatin
Vicenistatin is a macrolactam antibiotic synthesized by '' Streptomyces halstedii'' HC34. It was originally isolated from this bacterium in 1993. It includes the unusual starter unit methylaspartate.
