P.16 left column 2nd paragraph: "Likewise, there is no known basis for
the high KCO2 of the cyanobacterial enzyme (Table 2). Finally, there is no defined reason why this enzyme does not exhibit ‘fallover’ i.e., the characteristic time-dependent decrease in enzymatic activity exhibited by the plant enzyme and most microbial form I enzymes. Indeed, comparisons of very closely related bacterial enzymes of Type IC clearly show very different enzymatic properties (Table 2), as eluded to earlier." Specificity factor for Rubisco (Ω (Ω=VcKo/VoKc), is the ratio of the catalytic efficiency (Vmax/Km) for the carboxylase (Vc/Kc) and oxygenase (Vo/Ko) reactions) |
