- Carnosine synthase
In
enzymology , a carnosine synthase (EC number|6.3.2.11) is anenzyme that catalyzes thechemical reaction :ATP + L-histidine + beta-alanine AMP + diphosphate + carnosine
The 3 substrates of this enzyme are ATP,
L-histidine , andbeta-alanine , whereas its 3 products are AMP,diphosphate , andcarnosine .This enzyme belongs to the family of
ligase s, specifically those forming carbon-nitrogen bonds as acid-D-amino-acid ligases (peptide synthases). The systematic name of this enzyme class is L-histidine:beta-alanine ligase (AMP-forming). Other names in common use include carnosine synthetase, carnosine-anserine synthetase, homocarnosine-carnosine synthetase, and carnosine-homocarnosine synthetase. This enzyme participates in 4 metabolic pathways:urea cycle and metabolism of amino groups ,alanine and aspartate metabolism ,histidine metabolism , andbeta-alanine metabolism .References
