Francisco Javier Las Heras-Vázquez is an Associate Professor at the Department of Chemistry and Physics, University of Almería. He graduated in Chemistry from the University of Almeria in 1994 and obtained a PhD in Chemistry from the same university in 1998. After post-doctoral work in 2001 at the Institute of Biochemical Engineering of the University of Stuttgart, he returned to the University of Almeria as an Assistant Professor in the research group of Prof. Felipe Rodriguez-Vico. In 2004, he was appointed Associate Professor in Biochemistry and Molecular Biology until now. His work has been focused on the development of multi-enzymatic systems for the production of optically pure alpha and beta-amino acids as precursors of antibiotics and other compounds of interest. Biotransformation systems have been developed based on enzymatic cascades made up of two, three, or four enzymes, which have transformed cheap substrates into products with high added value, such as the aforementioned amino acids. Also, he has participated in the study of recombinant enzymes in different systems, both in their native and mutated forms. More recently, he has focused on the immobilization of the developed biotransformation systems in order to confer new properties, such as increased thermostability and reuse of immobilized biocatalysts.
