描述
ADP-ribose 1"-2" cyclic phosphate is a cyclic phosphate nucleotide that arises from tRNA processing. In eukaryotic cells, pre-tRNAs spliced by a pathway that produces a 3',5'-phosphodiester, 2'-phosphomonoester linkage contain a 2'-phosphate group adjacent to the tRNA anticodon. This 2'-phosphate is transferred to NAD to give adenosine diphosphate (ADP)-ribose 1", 2"-cyclic phosphate (Appr>p), which is subsequently metabolized to ADP-ribose 1'-phosphate (Appr-1'p). The latter reaction is catalyzed by a cyclic phosphodiesterase (CPDase). (PMID: 9148938). One molecule of ADP-ribose 1",2"-cyclic phosphate (Appr>p) is formed during each of the approximately 500 000 tRNA splicing events. [HMDB]
