===Pseudomonas fluorescens aryl esterase===

~~==Overview==~~

<!--

The ~~structure of PFE~~, ~~an aryl esterase from Pseudomonas fluorescens~~, ~~has been solved~~ to ~~a resolution of 1.8 A by X-ray diffraction and shows a characteristic alpha/beta-hydrolase fold. In addition to catalyzing~~ the hydrolysis of esters in vitro, PFE also shows low bromoperoxidase activity. PFE shows highest structural similarity, including the active-site environment, to a family of non-heme bacterial haloperoxidases, with an r.m.s. deviation in 271 C(~~alpha) atoms between PFE and its five closest structural neighbors averaging 0.8 A. PFE has far less similarity (r.m.s~~. ~~deviation in 218 C(alpha) atoms of 5~~.~~0 A~~) ~~to P. fluorescens carboxyl esterase. PFE favors activated esters with small acyl groups~~, ~~such as phenyl acetate~~. ~~The X~~-~~ray structure of PFE reveals a significantly occluded active site. In addition, several residues, including Trp28 and Met95, limit the size of the acyl~~-~~binding pocket, explaining its preference for small acyl groups.~~

The X-ray structure of PFE reveals a significantly occluded active site. In addition, several residues, including Trp28 and Met95, limit the size of the acyl-binding pocket, explaining its preference for small acyl groups.
