One Carbon Group Transferases, also known as OCGTs, are a group of enzymes that play a crucial role in various biochemical reactions. These enzymes contribute to the transfer of a one-carbon group, such as a methyl group (-CH3), from one molecule to another. While commonly referred to as OCGTs, there are several other synonymous terms to describe these enzymes. They are also known as methyltransferases, methylases, carbon group transferases, or more specifically, methyl-group transferases. These alternative terms highlight the fundamental function of these enzymes in the transfer of one-carbon groups. Understanding the various synonyms for One Carbon Group Transferases aids in better comprehension and effective communication in scientific research and discussions.
