RuBisCo activase (Rca) is a catalytic chaperone involved in modulating the activity of RuBisCo (key enzyme of photosynthetic pathway). Here, we identified eight novel transcripts from wheat through data mining predicted to be Rca and cloned a transcript of 1.4 kb from cv. HD2985, named as TaRca1 (GenBank acc. no. KC776912). Single copy number of TaRca1 was observed in wheat genome. Expression a...
Rubisco’s catalytic chaperone, Rubisco activase (Rca), uses the energy from ATP hydrolysis to restore catalytic competence to Rubisco. In Arabidopsis (Arabidopsis thaliana), inhibition of Rca activity by ADP is fine tuned by redox regulation of the a-isoform. To elucidate the mechanism for Rca regulation in species containing only the redox-insensitive b-isoform, the response of activity to ADP...
In Arabidopsis, oxidation of the large (46-kDa) isoform activase to form a disulfide bond in the C-terminal extension (C-extension) significantly increases its ADP sensitivity for both ATP hydrolysis and ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) activation, thereby decreasing both activities at physiological ratios of ADP/ATP. In this study, we demonstrate that the C-extension o...
Several cDNAs encoding ribulose-1,5-bisphosphate carboxylase/oxygenase activase (Rubisco activase, RCA) were isolated from a maize (Zea mays L.) leaf cDNA library. Although all the cDNAs encoded the same polypeptide, the RCA beta isoform, they showed two different downstream-like elements (DST-like) at their 3' untranslated regions (UTRs). The Zmrca1 cDNAs had the subdomain I, and II and the Zm...
