SPR has several biochemical functions, for example, NADP binding, aldo-keto reductase (NADP) activity, sepiapterin reductase activity. Some of the functions are cooperated with other proteins, some of the functions could acted by SPR itself. We selected most functions SPR had, and list some proteins which have the same functions with SPR. You can find most of the proteins on our site.
