Other name(s): Carnosine synthetase.
Comments: This enzyme was thought to form Amp, but studies with highly purified enzyme proved that it forms Adp. Carnosine is a dipeptide that is present at high concentrations in skeletal muscle and the olfactory bulb of vertebrates. It is also found in the skeletal muscle of some invertebrates. The enzyme can also catalyze the formation of homocarnosine from 4-aminobutyrate and L-histidine, with much lower activity.
