Place the following steps in order to describe the catalytic mechanism of the enzyme known informally as RuBisCo. 1. Conversion of ribulose-1,5-bisphosphate into its enediolate form II. Reverse aldol cleavage yields a 3-phosphoglycerate product III. Nucleophilic attack of CO2 by the enediolate intermediate IV. General base abstraction of the proton a to the carbonyl carbon of ribulose-1,5-bisphosphate V. Protonation of a carbanion yields a 3-phosphoglycerate product VI. Nucleophilic attack by water on the B-carbonyl carbon of the intermediate IV-III-III-V-VI O VI-II-I-III-IV-V O I-III-II-IV-VI-V O IV-VI-III-I-V-11 O IV-I-IIIVI-II-V
