Membrane association and kinase-like motifs of the RamC protein of Streptomyces coelicolor.
The protein RamC is required for the production of the spore-forming cells called aerial hyphae by the filamentous bacterium Streptomyces coelicolor. We showed that RamC, which contains several weakly predicted membrane-spanning sequences, is located exclusively in the S. coelicolor membrane. By constructing site-directed mutants in the cloned ramC gene and complementing a ramC null mutant, we showed that protein kinase-like sequence motifs in the amino-terminal half of the protein are required for function in vivo. These data suggest that RamC is a membrane-associated receptor kinase.
