Guanosine 2',3'-cyclic phosphate
IUPAC 名称
9-[(3aR,4R,6R,6aR)-2-hydroxy-6-(hydroxymethyl)-2-oxo-tetrahydro-2H-2λ⁵-furo[3,4-d][1,3,2]dioxaphosphol-4-yl]-2-amino-6,9-dihydro-3H-purin-6-one
描述
2',3'-Cyclic GMP is a cyclic guanosine derivative that is a precursor to 3'-GMP. The enzyme 2'3'-cyclic-nucleotide 2'-phosphodiesterase (E.C. 3.1.4.16) catalyses the hydrolysis of both 2',3'-cyclic AMP and 2',3'-cyclic GMP into 3'-AMP and 3'-GMP, respectively, at the 3'-terminal of RNA. 2',3'-cyclic phosphate termini are produced, as either intermediates or final products, during RNA cleavage by many different endoribonucleases. The enzyme RNA 3'-phosphate cyclase also converts the 3'-terminal phosphate in RNA into the 2',3'-cyclic phosphodiester in the ATP-dependent reaction which involves formation of the covalent cyclase-AMP and the RNA-N3' pp5' A intermediates (PMID: 10397337). This enzyme could be involved in the maintenance of cyclic ends in tRNA splicing intermediates or in the cyclization of the 3' end of U6 snRNA (PMID: 9184239). Guanosine-2',3'-cyclic phosphate is capable of blocking DNA synthesis in vitro (PMID: 7528887). 2', 3'-cGMP seems to preferentially stimulate mature T-cells while 3', 5'-cGMP preferentially acts on B-cells (PMID: 163786) [HMDB]
