Protein attributes

Sequence length254 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

Catalyzes the formation of N(7)-methylguanine at position 46 (m7G46) in tRNA By similarity. HAMAP-Rule MF_01057

Catalytic activity

S-adenosyl-L-methionine + guanine46 in tRNA = S-adenosyl-L-homocysteine + N(7)-methylguanine46 in tRNA. HAMAP-Rule MF_01057

Pathway

tRNA modification; N(7)-methylguanine-tRNA biosynthesis. HAMAP-Rule MF_01057

Sequence similarities

Belongs to the class I-like SAM-binding methyltransferase superfamily. TrmB family.

Sequence caution

The sequence CAE31010.1 differs from that shown. Reason: Erroneous initiation.
