31. This gene encodes a GTP-specific beta subunit of succinyl-CoA synthetase . 32. Each of the 20 amino acids are recognized by its specific aminoacyl-tRNA synthetase . 33. CTP is subsequently formed by amination of UTP by the catalytic activity of CTP synthetase . 34. Glutamine Synthetase uses ammonia produced by nitrate reduction, amino acid degradation, and photorespiration. 35. It is synthesized by gramicidin S synthetase . 36. Expression of argininosuccinate synthetase in the intestines ceases after two to three years of life. 37. CTP ( cytidine triphosphate ) synthetase catalyzes the last committed step in pyrimidine nucleotide biosynthesis: 38. PA01 genome and both copies appear to be located upstream of predicted glutamine synthetase genes. 39. This enzyme is also called "'5-phosphoribosylimidazoleacetate synthetase " '. 40. Glutaminyl-tRNA synthetase belongs to the class-I aminoacyl-tRNA synthetase family.
