<prompt> Enzyme of Urea cycle deficient in Brain is :ArginaseCarbamoyl phosphate synthetase IOrnithine Trans CarbamoylaseArgino Succinate Lyase  <response>: 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
