DESCRIPTION

Also known as TRMI_PYRAB, trmI, pimT-like. Catalyzes the S-adenosyl-L-methionine-dependent formation of N(1)-methyladenosine at position(s) 57 (m1A57) and 58 (m1A58) in the T-loop of some tRNAs. Methylates the first adenine of an AA sequence. Homotetramer composed of a dimer of dimers; disulfide-linked. Disulfide bonds are important for the stability of TrmI at extreme temperatures.
