rbcL — Beta vulgaris subsp. vulgaris

Summary

BVRB_027550 (symbol rbcL) on sugar beet chromosome 111946 encodes the large subunit of ribulose-bisphosphate carboxylase (RuBisCO) and has EC 4.1.1.39. The product possesses RuBisCO and monooxygenase activities, binds magnesium, and is localised to the plastid. It is associated with the reductive pentose-phosphate cycle, photorespiration, and leaf development. Studies of related genes in other species link the rbcL family to chlorophyll content and fruit colour, though these associations are not yet established in sugar beet.
