Dr. Marc Garcia-Borràs

Dr. Marc Garcia-Borràs (b. 1988, Sant Feliu de Guíxols) obtained his PhD with academic honors at the University of Girona (2012-2015, Cum Laude, Extraordinary PhD Award), under the supervision of Prof. Miquel Solà and Dr. Josep M. Luis. He worked on the computational study of the structure and reactivity of endohedral (metallo-)fullerenes. After a short (6 months) postdoc stay in the group of Dr. Osuna (UdG, Spain), he joined the group of Prof. K. N. Houk at UCLA (USA) as a postdoc for 3 years (Jan. 2016 – Jan. 2019) supported by a prestigious Ramón Areces Postdoctoral Fellowship (to work on the computational modelling and design of new (metallo-)enzyme catalyzed reactions. He was awarded the “2018 UCLA Department of Chemistry and Biochemistry Postdoctoral Research Award”. In February 2019 he returned to Spain as a Juan de la Cierva -Incorporación (JdC-I) research fellow to start his independent research program on biocatalysis at the UdG. Very recently, he was awarded a Beatriu the Pino?s MSCA-COFUND grant (Feb.-2020), and he is also PI of a Spanish MICINN “I+D+i de Generación de Conocimiento 2019” project (PID2019-111300GA-I00, 3 years 01/06/2020 – 31/05/2023). Marc was finalist at the European Young Chemistry Awards (EYCA) 2020 (EuChemS) Early Career Researcher level.
In September 2020 he became an independent Principal Investigator at the IQCC (UdG).

Research overview

Enzymatic reactive intermediates are species involved in biocatalytic cycles that are not so stable and exhibit short lifetimes. Catalytic promiscuity refers to the ability of an enzyme to catalyze, in addition to its native function, reactions involving different substrates and/or that proceed via different transition states and different reaction pathways. Enzymatic intermediates are sometimes found to be the source of enzyme catalytic promiscuity, since different reaction pathways can diverge from these generated species. Consequently, controlling the behavior of such reactive species could provide new routes to access to new non-natural biocatalytic functions.
In this research program new computational protocols to study and characterize reactive intermediates formed over the course of enzyme catalytic pathways will be developed. These protocols will rely on different multiscale computational approaches that will be combined to account for different factors that play key roles on the formation and stabilization of enzymatic reactive intermediates and that control their subsequent reactivity. State-of-the-art computational techniques including DFT calculations, Molecular Dynamics (MD) simulations, QM/MM calculations, and direct quasi-classical reaction dynamics MD simulations, among others, will be part of such protocols. In particular, enzymatic systems involving metalloenzymatic and photobiocatalytic intermediates will be targeted.
Also, molecular biology experiments and structural chemical characterization of the biocatalytic products will be performed in order to assess the computational predictions and designs, providing further guidance for computational modelling.
Finally, the knowledge acquired will be used to computationally design new enzymes for catalyzing new-to-nature reactions interesting for synthetic purposes in a more rational and efficient manner.
