... the activating interaction of AdoMet with TS may attenuate the changes in the flux of threonine due to a modification of the level of AdoMet. Indeed, upon an increase in the level of AdoMet, TS is activated ... independent of what happens on the cystathionine side. The Phser branch-point combines the divergence of two fluxes (fluxes of cystathionine and threonine) with the converg...
