| Enzyme Function | FUNCTION: Esterase whose enzymatic activity is required for rhamnolipid production, all kinds of cell motility (swimming, swarming, and twitching), and biofilm formation; the exact role of EstA in these processes is unclear. In vitro, has pronounced esterase activities towards p-nitrophenyl esters of short acyl chain length (C4-C6) and Tween detergents. Also shows relatively high activity towards beta-naphthyl butyrate, whereas its activities towards triacylglycerols and acyls-CoA are negligible. {ECO:0000269|PubMed:17631636, ECO:0000269|PubMed:20931591}. |
