Abstract: Obesity is a common clinical problem in most developed nations and is also rapidly becoming a major health concern in developing nations. Overweight individuals frequently suffer from several metabolic disorders such as insulin resistance, type 2 diabetes and dyslipidemia. This invention discloses proof of principle for the role PPAR&dgr; (also known as &bgr;) plays in the development of diet-induced obesity. In accordance with the present invention, a new method for treating obesity, insulin resistance and hyperlipidemia through administration of a pharmaceutical composition containing a chemical agent that antagonizes the function of PPAR&dgr;(&bgr;) protein, decreases PPAR&dgr;(&bgr;) gene expression and or transactivation of PPAR&dgr;(&bgr;) target gene expression is disclosed.

The invention also provides nucleic acid sequences, vectors, and host cells useful in the production of this amidase. The glutaryl 7-ACA amidase can be used for the preparation of 7-aminocephalosporanic acid.
