AC O98949; DT 01-MAY-1999 (TrEMBLrel. 10, Created) DT 01-MAY-1999 (TrEMBLrel. 10, Last sequence update) DT 01-MAR-2001 (TrEMBLrel. 16, Last annotation update) DE RIBULOSE BISPHOSPHATE CARBOXYLASE LARGE CHAIN (EC 4.1.1.39). GN RBCL. OS Galdieria partita. OG Chloroplast. OC Eukaryota; Rhodophyta; Bangiophyceae; Porphyridiales; Porphyridiaceae; OC Galdieria. OX NCBI_TaxID=83374; RN [1] RP SEQUENCE FROM N.A. RA Tomizawa K.; RT "Structure and function study of ribulose-1,5-bisphosphate RT carboxylase/oxygenase of the red algae, Galdieria partita Tokara."; RL Submitted (SEP-1998) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: RUBISCO CATALYSES TWO REACTIONS: THE CARBOXYLATION OF D- CC RIBULOSE 1,5-BISPHOSPHATE, THE PRIMARY EVENT IN PHOTOSYNTHETIC CC CARBON DIOXIDE FIXATION, AS WELL AS THE OXIDATIVE FRAGMENTATION OF CC THE PENTOSE SUBSTRATE IN THE PHOTORESPIRATION PROCESS. BOTH CC REACTIONS OCCUR SIMULTANEOUSLY AND IN COMPETITION AT THE SAME CC ACTIVE SITE. CC -!- CATALYTIC ACTIVITY: D-RIBULOSE 1,5-BISPHOSPHATE + CO(2) = 2 3- CC PHOSPHO-D-GLYCERATE. CC -!- CATALYTIC ACTIVITY: D-RIBULOSE 1,5-BISPHOSPHATE + O(2) = 3- CC PHOSPHO-D-GLYCERATE + 2-PHOSPHOGLYCOLATE (BY SIMILARITY). CC -!- SUBUNIT: 8 LARGE CHAINS + 8 SMALL CHAINS. CC -!- SUBCELLULAR LOCATION: CHLOROPLAST (BY SIMILARITY). CC -!- SIMILARITY: BELONGS TO THE RUBISCO LARGE CHAIN FAMILY.
