Component: environment

Component: v_cystathionine

v_cystathionine = \frac{kcat_CGS_Cys CGS Cys}{Km_CGS_Cys + Cys} kcat_CGS_Cys = \frac{kcat_CGS}{1.0 + \frac{Km_CGS_Phser}{Phser} (1.0 + \frac{Pi}{Ki_CGS_Pi})} Km_CGS_Cys = \frac{km_CGS_Cys}{1.0 + \frac{Km_CGS_Phser}{Phser} (1.0 + \frac{Pi}{Ki_CGS_Pi})}

Component: v_Thr

v_Thr = \frac{TS kcat_TS Phser}{Km_TS + Phser} kcat_TS = \frac{kcat_TS_noAdoMet + kcat_TS_AdoMet \frac{{AdoMet}^{2.0}}{K1K2}}{1.0 + \frac{{AdoMet}^{2.0}}{K1K2}} Km_TS = \frac{250.0 \frac{1.0 + \frac{AdoMet}{0.5}}{1.0 + \frac{AdoMet}{1.1}}}{1.0 + \frac{{AdoMet}^{2.0}}{140.0}} (1.0 + \frac{Pi}{Ki_TS_Pi})
