Reaction: S-adenosyl-L-methionine + adenine22 in tRNA = S-adenosyl-L-homocysteine + N1-methyladenine22 in tRNA
Other name(s): TrmK; YqfN; Sp1610 (gene name); tRNA: m1A22 methyltransferase
Systematic name: S-adenosyl-L-methionine:tRNA (adenine22-N1)-methyltransferase
Comments: The enzyme specifically methylates adenine22 in tRNA.
