Partial purification and some properties of Guanosine Triphosphate Cyclohydrolase from Pseudomonas putida : GTP cyclohydrolase from pseudomonas
Pseudomonas putida에서 부분정제한 Guanosine Triphosphate Cyclohydrolase 의 특성에 관한 연구
Abstract
An enzyme, named GTP cyclohydorlase, that catalizes the hydrolytic removal of carbon No.S of GTP has been partially purified from extracts of Pseudomonas putida (IAM 1506). The enzyme exists in two molecuar weight forms : a high molecular weight form (150,000) and a low molecular weight from (40,000). The high molecular weight form has been purified 25-fold. Some of the properties of the enzyme are as follows : It functions optimally at pH8.0, and at
