Ribulose bisphosphate carboxylase large chain; Ribulose bisphosphate carboxylase (Rubisco) ...
1-99 2.89e-75

Ribulose bisphosphate carboxylase large chain; Ribulose bisphosphate carboxylase (Rubisco) plays an important role in the Calvin reductive pentose phosphate pathway. It catalyzes the primary CO2 fixation step. Rubisco is activated by carbamylation of an active site lysine, stabilized by a divalent cation, which then catalyzes the proton abstraction from the substrate ribulose 1,5 bisphosphate (RuBP) and leads to the formation of two molecules of 3-phosphoglycerate. Members of the Rubisco family can be divided into 4 subgroups, Form I-IV, which differ in their taxonomic distribution and subunit composition. Form I-III have Rubisco activity, while Form IV, also called Rubisco-like proteins (RLP), are missing critical active site residues and therefore do not catalyze CO2 fixation. They are believed to utilize a related enzymatic mechanism, but have divergent functions.

2,3-diketo-5-methylthiopentyl-1-phosphate enolase; Ribulose bisphosphate carboxylase like proteins (RLPs) similar to B. subtilis YkrW protein, have been identified as 2,3-diketo-5-methylthiopentyl-1-phosphate enolases. They catalyze the tautomerization of 2,3-diketo-5-methylthiopentane 1-phosphate (DK-MTP 1-P). This is an important step in the methionine salvage pathway in which 5-methylthio-D-ribose (MTR) derived from 5'-methylthioadenosine is converted to methionine.

2,3-diketo-5-methylthiopentyl-1-phosphate enolase; Members of this family are the methionine salvage pathway enzyme 2,3-diketo-5-methylthiopentyl-1-phosphate enolase, a homolog of RuBisCO. This protein family seems restricted to Bacillus subtilis and close relatives, where two separate proteins carry the enolase and phosphatase activities that in other species occur in a single protein, MtnC (TIGR01691).

Ribulose bisphosphate carboxylase like proteins, Rubisco-Form IV; Ribulose bisphosphate carboxylase (Rubisco) plays an important role in the Calvin reductive pentose phosphate pathway. It catalyzes the primary CO2 fixation step. Rubisco is activated by carbamylation of an active site lysine, stabilized by a divalent cation, which then catalyzes the proton abstraction from the substrate ribulose 1,5 bisphosphate (RuBP) and leads to the formation of two molecules of 3-phosphoglycerate. Members of the Rubisco family can be divided into 4 subgroups, Form I-IV, which differ in their taxonomic distribution and subunit composition. Form I-III have Rubisco activity, while Form IV, also called Rubisco-like proteins (RLP), are missing critical active site residues and therefore do not catalyze CO2 fixation. They are believed to utilize a related enzymatic mechanism, but have divergent functions, like for example 2,3-diketo-5-methylthiopentyl-1-phosphate enolase or 5-methylthio-d-ribulose 1-phosphate isomerase.

It catalyzes the primary CO2 fixation step. Rubisco is activated by carbamylation of an active site lysine, stabilized by a divalent cation, which then catalyzes the proton abstraction from the substrate ribulose 1,5 bisphosphate (RuBP) and leads to the formation of two molecules of 3-phosphoglycerate. Members of the Rubisco family can be divided into 4 subgroups, Form I-IV , which differ in their taxonomic distribution and subunit composition. Form II is mainly found in bacteria, and forms large subunit oligomers (dimers, tetramers, etc.) that do not include small subunits.
