| GTP cyclohydrolase II | Two C-N bonds are hydrolysed, releasing formate, with simultaneous removal of the terminal diphosphate. Group: Enzymes. Synonyms: guanosine triphosphate cyclohydrolase II; GTP-8-formylhydrolase. Enzyme Commission Number: EC 3.5.4.25. CAS No. 56214-35-8. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-4552; GTP cyclohydrolase II; EC 3.5.4.25; 56214-35-8; guanosine triphosphate cyclohydrolase II; GTP-8-formylhydrolase. Cat No: EXWM-4552. |  |
| GTP cyclohydrolase IIa | Requires Mg2+. This enzyme catalyses the hydrolysis of the imidazole ring of guanosine 5'-triphosphate, N7-methylguanosine 5'-triphosphate or inosine 5'-triphosphate. Xanthosine 5'-triphosphate and ATP are not substrates. It also catalyses the hydrolysis of diphosphate to form two equivalents of phosphate. Unlike GTP cyclohydrolase II (EC 3.5.4.25), this enzyme does not release formate, but does hydrolyse the diphosphate from GTP to phosphate. Group: Enzymes. Enzyme Commission Number: EC 3.5.4.29. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-4556; GTP cyclohydrolase IIa; EC 3.5.4.29. Cat No: EXWM-4556. | |
| 2-amino-5-formylamino-6-ribosylaminopyrimidin-4(3H)-one 5'-monophosphate deformylase | The enzyme catalyses the second step in archaeal riboflavin and 7,8-didemethyl-8-hydroxy-5-deazariboflavin biosynthesis. The first step is catalysed by EC 3.5.4.29 (GTP cyclohydrolase IIa). The bacterial enzyme, EC 3.5.4.25 (GTP cyclohydrolase II) catalyses both reactions. Group: Enzymes. Synonyms: ArfB. Enzyme Commission Number: EC 3.5.1.102. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-4381; 2-amino-5-formylamino-6-ribosylaminopyrimidin-4(3H)-one 5'-monophosphate deformylase; EC 3.5.1.102; ArfB. Cat No: EXWM-4381. | |
| diamino hydroxyphosphoribosylaminopyrimidine deaminase | The substrate is the product of EC 3.5.4.25 GTP cyclohydrolase II. Group: Enzymes. Enzyme Commission Number: EC 3.5.4.26. CAS No. 68994-19-4. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-4553; diamino hydroxyphosphoribosylaminopyrimidine deaminase; EC 3.5.4.26; 68994-19-4. Cat No: EXWM-4553. | |
| GTP cyclohydrolase IV | Requires Fe2+. A zinc protein. The enzyme is involved in methanopterin biosynthesis in methanogenic archaea. cf. GTP cyclohydrolase I (EC 3.5.4.16), GTP cyclohydrolase II (EC 3.5.4.25) and GTP cyclohydrolase IIa (EC 3.5.4.29). Group: Enzymes. Synonyms: MptA; GTP cyclohydrolase MptA. Enzyme Commission Number: EC 3.5.4.39. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-4567; GTP cyclohydrolase IV; EC 3.5.4.39; MptA; GTP cyclohydrolase MptA. Cat No: EXWM-4567. | |
