Crystallization (Commentary)

EC Number Crystallization (Comment) Organism
3.2.1.21 structures of Lin1840 wild-type and mutant D270A in complexes with sophorose and laminaribiose. Residue Arg572 forms many hydrogen bonds with sophorose and laminaribiose at subsite +1, a key factor for substrate selectivity. The opposite side of subsite +1 from Arg572 is connected to a large empty space, which may be subsite +2 for the binding of sophorotriose Listeria innocua Clip11262
