Pseudomonas

Pathogenicity and Biotechnology (3d phase)

New Pseudomonas enzymes acting on 4-substituted but-2-en-4-olides on the third period of the International Research Training Group "Pseudomonas: Pathogenicity and Biotechnology"

 

AG Microbial Interactions and Processes has been participating since the beginning of this European Graduate

School (EGK) carrying out studies on Pseudomonas sp. strain MT1, a chloroaromatic degrader: In this phase the project is entitled:

New Pseudomonas enzymes acting on 4-substituted but-2-en-4-olides

Background and objectives:

4-Chloromuconolactone (4-carboxymethyl-4-chlorobut-2-en-4-olide) and protoanemonin (4-methylenbut-2-en-4-olide) are key intermediates in a 4-membered community degrading chlorosalicylate by a complex net of metabolic interactions and are subject to transformation by either a new type of hydrolase termed trans-dienelactone hydrolase (acting on 4-chloromuconolactone) or thus far unknown enzymes. The proposed project aims on elucidating the structure, mechanism and substrate specificity of the new type of supposedly metal-dependent hydrolase and on the characterization of the metal centers and on the elucidation of the metabolic pathway and enzymes involved in protoanemonin degradation.
