Protein phosphorylation in purple photosynthetic bacteria
Abstract
Endogenous protein phosphorylation was shown in both in vitro and in vivo experiments in R. rubrum and in other purple photosynthetic bacteria. Among the substrates of this protein kinase activity the apoproteins of the light harvesting complex were tentatively identified. Phosphoamino acid analysis revealed the presence of phosphoserine, phosphothreonine and phosphotyrosine in R. rubrum. A tyrosine kinase was partially purified in the same bacteria.
