Protein Name: Bifunctional riboflavin biosynthesis protein RIBA 1, chloroplastic

UniprotKB/SwissProt ID: P47924 (P47924)

Gene Name: RIBA1

Organism: Arabidopsis thaliana (Mouse-ear cress)

Function: Involved in riboflavin biosynthesis. Catalyzes both the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate and the conversion of GTP to 2,5-diamino-6-ribosylamino-4(3H)-pyrimidinone 5'-phosphate (DARP), formate and pyrophosphate. RIBA2 and RIBA3 together are not able to complement the loss of function of RIBA1

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Plastid, chloroplast
