Molecular biology of the C3 photosynthetic carbon reduction cycle

Abstract

In recent years the enzymes of the C3 photosynthetic carbon reduction (PCR) cycle have been studied using the techniques of molecular biology. In this review we discuss the primary protein sequences and structural predictions that have been made for a number of these enzymes, which, with the input of crystallographic analysis, gives the opportunity to understand the mechanisms of enzyme activity.The genome organisation and gene structure of the PCR enzymes is another area which has recently expanded, and we discuss the regulation of the genes encoding these enzymes and the complex interaction of various factors which influence their expression.
