Structure of Pseudomonas aerugionsa PvdQ bound to octanoate

Template:ABSTRACT PUBMED 21892836

Function

[PVDQ_PSEAE] Catalyzes the deacylation of acyl-homoserine lactone (AHL or acyl-HSL), releasing homoserine lactone (HSL) and the corresponding fatty acid. Possesses a specificity for the degradation of long-chain acyl-HSLs (side chains of 11 to 14 carbons in length). Degrades 3-oxo-C12-HSL, one of the two main AHL signal molecules of P.aeruginosa, and thereby functions as a quorum quencher, inhibiting the las quorum-sensing system. Therefore, may enable P.aeruginosa to modulate its own quorum-sensing-dependent pathogenic potential. Also appears to be required for pyoverdin biosynthesis.[1] [2] [3]

About this Structure

3l91 is a 2 chain structure with sequence from Pseudomonas aeruginosa. Full crystallographic information is available from OCA.
