... by marine phytoplankton ( e.g ., Bidigare et al. , 1997 ; Hayes, 2001 ). My Ph.D. research was to purify the enzyme Rubisco from various organisms and measure the isotopic fractionation in vitro. Harmon Craig wrote the first blockbuster paper on “carbon isotopes in everything” from diamonds...

Figure 2.2 I purified Rubisco for most of the experiments I conducted for measuring carbon isotope fractionation. At that time, we were concerned that other enzymes could modify the product, PGA, and change fractionation values. Modified from Estep et al. (1978a) .

Figure 2.4 Different forms of Rubisco from various organisms. Plants, algae, cyanobacteria, and some proteobacteria have enzymes with both large and small subunits (Form I) (see Tabita et al. , 2007 ). Different Rubisco forms (II, III, and IV) fractionate carbon isotopes slightly different

... in situ work with Rubisco. If conditions are right, Rubisco has the potential to fix O 2 , rather than CO 2 . This can occur when temperatures are high, and the plant has made an excess of oxygen that might damage the plant via free radical production. At that time, we could not account...

...,/CO, ratios lead in evolution to a number of mechanisms whereby CO, supply to RUBISCO (see below) could be increased over that due to diffusion. On land, this mechanism (C, photosynthesis) also serves to economize on water lost per unit dry-weight gain in a given environment. In summary, the evolution...

... well understood ( Vance and Spalding, 2005 ; Woodger et al., 2005 ), since oxygen competitively inhibits CO 2 fixation by RuBisCO and promotes photorespiration, the light-dependent release of CO 2 by photosynthetic organisms ( Bowes et al., 1971 ). The expectation, therefore, is that times...

.... Next is methane. Natural methane sources are almost entirely biological nowadays. In the pre-Holocene world, methane sources included methanogenic archaea ( Woese 1987 ) living in wetland muds, in ruminants and in termites, and also vegetation fires that released rubisco-captured carbon back to the air...

... of organisms, CO 2 is fixed by the Rubisco enzyme (ribulose 1,5-biphosphate carboxylase-oxygenase). In bryophytes, the site of carboxylation is within the numerous chlorophyll-bearing cells that line the gas-filled chambers of the pores. In lichens, carboxylation occurs within the photobiont, and carbon...
