Jr., Hancock R.E.W., Lory S., Olson M.V.; RT "Complete genome sequence of Pseudomonas aeruginosa PAO1, an opportunistic RT pathogen."; RL Nature 406:959-964(2000). CC -!- FUNCTION: Involved in the catabolism of short chain fatty acids (SCFA) CC via the tricarboxylic acid (TCA)(acetyl degradation route) and probably CC the 2-methylcitrate cycle I (propionate degradation route). Catalyzes CC the reversible isomerization of citrate to isocitrate via cis- CC aconitate. Could catalyze the hydration of 2-methyl-cis-aconitate to CC yield (2R,3S)-2-methylisocitrate. The apo form of AcnA functions as a CC RNA-binding regulatory protein. {ECO:0000250|UniProtKB:P09339, CC ECO:0000250|UniProtKB:Q8ZP52}.
