Abstract

Ribulose 1, 5-bisphosphate carboxylase (RuBPCase) has a central role in the C and N economy of many crop plants. In C3 plants, RuBPCase catalyzes the primary rate-limiting step in CO2 fixation (Jensen and Bahr, 1977; Bahr and Steffens, this volume). RuBPCase also functions as a storage protein and is rapidly degraded during leaf senescence (Friedrich and Huffaker, 1980; Wittenbach et al., 1980). The catalytic properties of RuBPCase and other Calvin-cycle enzymes have been thoroughly reviewed (Jensen and Bahr, 1977; Bahr and Steffens, this volume; Buchanan, this volume). Likewise, the regulation of RuBPCase degradation has been discussed (Huffaker and Miller, 1978; Miller and Huffaker, this volume; Thomas and Stoddart, 1980). Therefore, this article will focus mainly on the role of RuBPCase as a storage protein and on the relationship between RuBPCase concentration and photosynthesis.
