Glucokinase regulatory protein (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 capped by an alpha-helical lid domain (Pfam:PF20741). This entry represents the second SIS domain from GKRP [1].
Glucokinase regulatory protein N-terminal SIS domain
This domain is found N-terminal in glucokinase regulatory protein (GKRP) and related proteins. GKRP regulates glucokinase and it is activated by fructose 6-phosphate and inactivated by fructose 1-phosphate. It consists of two topologically identical ...
This domain is found N-terminal in glucokinase regulatory protein (GKRP) and related proteins. GKRP regulates glucokinase and it is activated by fructose 6-phosphate and inactivated by fructose 1-phosphate. It consists of two topologically identical SIS domains and and alpha-helical lid domain [1-4].
C-terminal lid domain of glucokinase regulatory protein
This domain is found at the C terminus of Glucokinase regulatory protein (GKRP) from animals and N-acetylmuramic acid 6-phosphate etherase (MurQ) from bacteria. GKRP binds Glucokinase (GK) mainly through hydrophobic interactions, functioning as an al ...
This domain is found at the C terminus of Glucokinase regulatory protein (GKRP) from animals and N-acetylmuramic acid 6-phosphate etherase (MurQ) from bacteria. 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].
Hexokinase (EC:2.7.1.1) contains two structurally similar domains represented by this family and Pfam:PF00349. Some members of the family have two copies of each of these domains.
