This is the FKBP-like domain found towards the N-terminal of TR61B (tRNA (adenine(58)-N(1))-methyltransferase from human and similar proteins. This mitochondrion-specific protein catalyses the formation of N1-methyladenine at position 58 (m1A58) in various tRNAs [1] and the formation of 1-methyladenosine at position 947 of mitochondrial 16S ribosomal RNA which is most likely important for mitoribosomal structure and function [2]. TR61B is most similar to bacterial TrmI than to eukaryotic Trmt61A, according to phylogenetic tree analysis [1]. The function of this domain is not clear but it may be necessary for overall folding and full enzymatic activity.	Domain
