The active site is not specific for its target molecule; competition with oxygen may inhibit net biomass production by 50 percent.
It is composed of between 2 and 16 subunits, but unlike most multi-subunit enzymes, it is not allosteric. The active site consists of three amino acid residues, one a carbamate derivative of lysine complexed to a magnesium ion. The active site is not specific for its target molecule; competition with oxygen may inhibit net biomass production by 50 percent. This enzyme attaches CO2 to ribulose biphosphate at the start of the Calvin cycle. FTP, name this plant enzyme, the most abundant on earth.
