Streptococcus mutans

physiological function

the N-terminal region of YcbY adds the m2G2445 modification, while the C-terminal region of YcbY is responsible for the m7G2069 methylation on the opposite side of the same helix, H74. YcbY enzyme is an example of a methyltransferase catalyzing two mechanistically different types of RNA modification
