This award was part of a collaborative effort to integrate studies of the structure, physiology and biochemistry of Synechocystis sp. PCC 6803 toward a functional model of the organism, awarded under the 'Microbial Cell Project' initiative, later incorporated into the Genomes to Life program. As indicated in the original proposal, the work at UCLA covered the proteomics sub-section of the project, complementing ultrastructural and physiological studies of mutant cell lines.
