RT   "Organization and expression of two tandemly oriented genes encoding
RT   ribulosebisphosphate carboxylase/oxygenase activase in barley.";
RL   J. Biol. Chem. 266:4677-4685(1991).
CC   -!- FUNCTION: Activation of RuBisCO (ribulose-1,5-bisphosphate
CC       carboxylase/oxygenase; EC 4.1.1.39) involves the ATP-dependent
CC       carboxylation of the epsilon-amino group of lysine leading to a
CC       carbamate structure.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast stroma.
CC   -!- SIMILARITY: Belongs to the RuBisCO activase family. {ECO:0000305}.
