HisZ is composed of two domains for the catalytic reaction and for anticodon binding. In contrast to other class-II aminoacyl-tRNA synthetases it lacks the essential editing domain. The C-terminal anicodon binding domain consists of three-stranded parallel beta-sheet flanked on each side with helices.	Domain
