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 ... Web16 aug. 2012 · Thus, a functional methylcitrate cycle and isocitrate/methylisocitrate lyase activity are required for mycobacterial growth on propionate. Moreover, the fact that these enzymes (isocitrate lyase, methylcitrate dehydratase, and methylcitrate synthase) are absent in mammals makes them promising as potential drug targets.

Web11 mei 2024 · Studies on prp- UV mutants have indicated that at least two pathways of propionate catabolism may act on B. sacchari: the α-oxidation pathway and the 2-methylcitrate cycle (2MCC). The presence of the genes and the functionality of 2MCC were observed, however the α-oxidation remained unproven. Web5 feb. 2015 · The induction of the methylcitrate cycle and the slight repression of icd1 (BCG3409c; Rv3339c), encoding an isocitrate dehydrogenase, suggests that the oxidative part of the citric acid cycle is bypassed in favor of this pathway (Additional file 6 ).
