TI  - Polyhydroxyalkanoate accumulation in Streptomyces coelicolor affected by SCO7613
gene region
AB  - Polyhydroxyalkanoate (PHA) is stored as an important carbon and energy source in bacterial cells. For biomedical applications, gram-positive bacteria can be better sources of PHAs, since they lack outer membrane lipopolysaccharide. Although gram-positive
Streptomyces coelicolor A3(2) has been indicated as a high potential PHA producer, phaC gene that encodes the key enzyme PHA synthase in the metabolic pathway is not determined in its genome. BLAST search results of the GenBank database argued that SCO7613 could
specify a putative polyhydroxyalkanoate synthase (PhaC) responsible for PHA biosynthesis. Deduced amino acid sequence of SCO7613
showed the presence of conserved lipase box like sequence, 555GASAG559, in which serine residue was present as the active nucleophile.
Present study describes deletion of putative S. coelicolor phaC gene via PCR dependent method. We showed that SCO7613 is not an
essential gene in S. coelicolor and its deletion affected PHA accumulation negatively although it is not ceased. Transcomplementation
abolished the mutant phenotype, demonstrating that the decrease in PHA resulted from the deletion of SCO7613.
