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. we found this enzyme in chloroplast and in amyloplast.
Function
[SSG1_ORYSJ] Required for the synthesis of amylose in endosperm.[HAMAP-Rule:MF_00484]
Publication Abstract from PubMed
The catalytic domain of rice (Oryza sativa japonica) granule bound starch synthase I (OsGBSSI-CD) was overexpressed and the three-dimensional structures of the ligand-free and ADP-bound forms were determined. The structures were similar to those reported for bacterial and archaeal glycogen synthases, which belong to glycosyltransferase family 5. They had Rossmann fold N- and C-domains connected by canonical two-hinge peptides, and an interdomain disulfide bond that appears to be conserved in the Poaceae plant family. The presence of three covalent linkages might explain why both OsGBSSI-CD structures adopted only the closed domain arrangement.

Disease
The protein 3vuf has allergenic properties, for example in mammals it can bind to Immunoglobulin E (IgE) causing an allergic response.
