Identification of a chloroplast-encoded secA gene homologue in a chromophytic alga: possible role in chloroplast protein translocation.

abstract：:Cyh3 and cyh4, multiple drug resistant strains of Schizosaccharomyces pombe, show a much reduced uptake of trichodermin, chloramphenicol, cycloheximide, L-lysine, glycine, L-threonine, L-glutamine, L-arginine and L-glutamic acid when compared to wild type. The plasma membrane and mitochondrial ATPase activities of the...
