rbcL — Brassica juncea

Summary

BJUB05G22220S (rbcL) in Indian mustard (Brassica juncea) on chromosome B05 encodes the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). The protein contains RuBisCO large-subunit N- and C-terminal domains and is annotated with RuBisCO activity, magnesium binding, and monooxygenase activity. This gene is associated with the reductive pentose-phosphate cycle, photorespiration, photoprotection, chlorophyll fluorescence, and digestion. It is also linked to chlorophyll content and salt tolerance (SALTTL). The encoded product localises to the chloroplast. Related genes in other species link RuBisCO large-subunit sequences to the enzyme class EC 4.1.1.39.
