3vuf is a 1 chain structure protein which is synthesized by the Japanese rice (Oryza sativa japonica). it’s an enzyme, more accurately a transferase. It’s a NDP-glucose--starch glucosyltransferase, which is involved in the synthesis of amylose in the rice. This enzyme is located chloroplast and in amyloplast.
The 3vuf protein is 609 amino acids long and weighs 66 476 Da.
Function
The protein have a role of transferase, more accurately it is a NDP-glucose--starch glucosyltransferase, which catalyse the reaction below :
This is a reaction allowing the extension of amylose. It has a major role in the pathway starch biosynthesis.
[SSG1_ORYSJ] Required for the synthesis of amylose in endosperm.[HAMAP-Rule:MF_00484]
Structural highlights
This protein is an enzyme, which is formed from one monomer and can bind to ADP. It binds to the ADP-glucose with amino acids 97,100, 408, 413,462 and 492. This allow the formation of an hydrophobic pocket in which ADP-glucose can binds to and in which he is protected from water and hydrolyse. we can also see that 3vuf can binds sulfate. This hydrophobic cage is allowed by the beta sheets and alpha helices that the protein have.
3vuf is a 1 chain structure with sequence from Japanese rice. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
