Enzyme of Urea cycle deficient in Brain is :
Arginase
Carbamoyl phosphate synthetase I
Ornithine Trans Carbamoylase
Argino Succinate Lyase
Enzyme of Urea cycle deficient in Brain is Ornithine Trans Carbamoylase (OTC). This enzyme catalyses the formation of citrulline from carbamoyl phosphate and ornithine. Arginase is absent in kidneys (option -1) CPS-1 is the RLE enzyme (option 2) Argino Succinate Lyase breakdown arginosuccinate in to arginine and fumarate. (option 4)
