Metabolite Identification
Common NameGuanosine 2',3'-cyclic phosphate
Description2',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. 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 ).

Chemical Taxonomy
Description belongs to the class of organic compounds known as glycosphingolipids. These are sphingolipids containing a saccharide moiety glycosidically attached to the sphingoid base. Although saccharide moieties are mostly O-glycosidically linked to the ceramide moiety, other sphingolipids with glycosidic bonds of other types (e.g. S-,C-, or N-type) has been reported.
