Thus, six molecules of pga are produced.

Ribulose 1 5 bisphosphat. The specific radioactivity of the remaining substrate pool. Help pages, faqs, uniprotkb manual, documents, news archive and biocuration projects. It has a role as an escherichia coli metabolite and a plant metabolite.

It is an intermediate in photosynthesis. Kinetic properties show some difference between c 3 and c. Rubp is used to identify, differentiate and characterize ribulose bisphosphate carboxylase (s)/oxygenase (s) (rubisco).

There is, however, a major catalytic flaw in the ability of this enzyme to convert co 2 to…. As the major enzyme of all photosynthetic cells, rubisco is the most abundant protein on earth. Interest in genetically engineering improvements in carboxylation catalytic efficiency and co2/o2 specificity has focused on the.

The primary structure of the large subunit of form i rubisco is well conserved; Despite the fact that it is the most abundant protein found on earth (3), rubisco’s catalytic efficiency is severely limited by the capacity to catalyze a competing o2fixation reaction. Of eight large subunits of 53.5 kda and eight small subunits of 13 kda (l 8 s 8 ).

This reaction occurs three times during each complete turn of the cycle;
