GKRP is trilobal in shape, consisting of two topologically identical sugar isomerase (SIS) domains capped by an alpha-helical lid domain (Pfam:PF20741). This entry represents the second SIS domain from GKRP [1].

GKRP binds Glucokinase (GK) mainly through hydrophobic interactions, functioning as an allosteric switch in blood glucose control by the liver [1]. GKRP is trilobal in shape, consisting of two topologically identical sugar isomerase (SIS) domains (Pfam:PF01380 and Pfam:PF13580) capped by an alpha helical C-terminal domain (this entry). The Lid domain consists of a bundle of seven alpha helices with a core that shows a UBA-like fold [2]. MurQ, which also shows a SIS domain, plays a key role in the peptidoglycane recycling pathway. Its crystal structure shows each monomer have an alpha-beta-alpha sandwich fold commonly found in regulatory proteins controlling the expression of genes involved in the synthesis of phosphosugars. The C-terminal domain of this protein (this entry) is comprised of five alpha helices [4].
