Research Interests
Professor Uribe is interested in the bioenergetics of photosynthesis and membrane transport. Recent research has centered on the function of chloroplast grana membranes in the energy conversion process. This research has included studies on the contribution of proton gradients and membrane potentials to the energy conversion process in photosynthetic systems. Energy-linked changes in the enzymatic activity and conformation of chloroplast coupling factor are also under investigation. Other areas of investigation include the study of plasmalemma and tonoplast localized ATPases and transport systems for inorganic and organic compounds.
