As shown in Fig. 1, propionate and oxaloacetate undergo an aldol condensation reaction to form 2-methylcitrate (2-MC), followed by an isomeri-zation to yield 2-methylisocitrate, and finally, a cleavage reaction yielding succinate and pyruvate.

(TCA)(acetyl degradation route) and probably the 2-methylcitrate cycle I (propionate degradation route). Catalyzes the reversible isomerization of citrate to isocitrate via cis- aconitate. Could catalyze the hydration of 2-methyl-cis-aconitate to yield (2R,3S)-2-methylisocitrate.
Webthe methylcitrate cycle, methylcitrate synthase, led to the identification of an operon necessary for propionate degra-dation. In E.coli and S.enterica this prp operon is composed of the genes prpB, prpC, prpDand prpE.PrpB and PrpC were identified as 2-methylisocitrate lyase [9] and methylcitrate synthase [7], respectively. PrpE was shown to WebVarious steps of this cycle (Fig. 14.3) occurring in higher plants especially during the germination of fatty seeds are as follows: (a) Reactions in Glyoxysome: (i) Acetyl-CoA produced after the β-oxidation of fatty acids (in glyoxysomes) condenses with oxaloacetic acid to form Citric Acid.
WebCitrate synthase activity. Specific Function. Involved in the catabolism of short chain fatty acids (SCFA) via the tricarboxylic acid (TCA) (acetyl degradation route) and via the 2-methylcitrate cycle I (propionate degradation route). Catalyzes the Claisen condensation of propionyl-CoA and oxaloacetate (OAA) to yield (2S,3S)-2-methylcitrate (2 ...
