Abstract The expression of the two different molecular forms (form I and form II) of ribulose-bisphosphate carboxylase/oxygenase (RuBisCO) in Rhodopseudomonas blastica during growth in batch on pyruvate–malate medium was investigated. During the early exponential phase of growth, only form I enzyme was synthesized. At the mid-exponential phase of growth, both forms were expressed, although form I enzyme was predominant. At the late exponential phase, form I and form II enzymes were synthesized but form II enzyme predominated. It is concluded that form I and form II RuBisCO enzymes in R. blastica are differentially expressed and this may be mediated by the level of CO2 in the growth medium.
