Protein attributes

Sequence length286 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.

Catalytic activity

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

Pathway

tRNA modification; N(7)-methylguanine-tRNA biosynthesis.

Subunit structure

Forms a complex with TRM82 By similarity.

Subcellular location

Nucleus By similarity.

Disruption phenotype

Significant reduction in pathogenicity on the host plants. Mutants develop penetration hyphae into cellophane, suggesting that appressoria of the mutants retain basic function for penetration. However, they fail to develop intracellular penetration hyphae into epidermis of the host plants. Ref.1

Sequence similarities

Belongs to the methyltransferase superfamily. TrmB family.
