RBCS — Pisum sativum

Summary

PSAT4G012920 (RBCS) encodes a protein containing the RuBisCO small subunit domain and is annotated with RuBisCO activity. It is associated with the reductive pentose-phosphate cycle, photorespiration, plastid translation, leaf development, and digestion. The enzyme catalyzes the reaction D-ribulose-1,5-bisphosphate+O2 -> 2-phosphoglycolate+3-phosphoglycerate. Localization evidence links the protein to the chloroplast. Studies of related genes in other species connect the family to photosynthetic efficiency and yield traits, though these associations are not directly established in pea.
