Figure 3. Multiple activity motifs overlay the pentose phosphate pathway and glycerol biosynthesis.
(a–e) Shown are the PPP and glycerol synthesis pathway (GSP) (a), along with activity motifs identified in four different conditions (b–e). Names in rectangles denote catalyzing enzyme; red denotes activation, green denotes repression; values denote the time of activation or repression onset. (b) Forward activation of the PPP and backward activation and funnel-same-time-activation of the GSP in response to a heat shock. (c) Forward-activation of PPP and backward-shutoff of GSP in response to menadione. (d) Forward activation of PPP and backward activation of GSP in response to diamide. (e) Forward shutoff and funnel-same-time forward shutoff in response to de-heating.
