"text": "<p>This family of proteins includes enzymes that are responsible for the methylation of cytidine residues in tRNA molecules. Specifically, they catalyze the 2'O-methylation of cytidine at the 32nd position, resulting in the formation of 2'O-methylcytidine. This modification is crucial for the proper functioning of tRNA. The enzymes exhibit specificity for cytidine and are part of a larger superfamily of SAM-binding methyltransferases. They are related to the RNA methyltransferase TrmH family, which shares similar structural motifs and catalytic functions.</p>",
