Metabolite Identification
Common Name1-Methylinosine
Description1-methylinosine is inosine carrying a methyl substituent at position 1 on the hypoxanthine ring. It has a role as a metabolite. It derives from an inosine. It is a modified nucleotide found at position 37 in tRNA 3' to the anticodon of eukaryotic tRNA. Shown that sequences are forced to adopt a hairpin conformation if one of the central 6 nt is replaced by the corresponding methylated nucleotide, such as 1-methylguanosine. In Vivo synthesis: Inosine-37 in tRNA is synthesised by a hydrolytic deamination-type reaction, catalysed by distinct tRNA:adenosine deaminases.
