StoPK-1, a serine/threonine protein kinase from the glycopeptide antibiotic producer Streptomyces toyocaensis NRRL 15009, affects oxidative stress response

The glycopeptide antibiotic-producing bacterium, Streptomyces toyocaensis NRRL 15009, has proteins phosphorylated on Ser, Thr, Tyr and His, implying the presence of a battery of associated kinases. We have identified the Ser/Thr protein kinase gene fragments stoPK-1, stoPK-2, stoPK-3 and stoPK-4 from S. toyocaensis NRRL 15009 by a polymerase chain reaction (PCR) strategy using oligonucleotide primers based on eukaryotic Ser/Thr and Tyr kinase …
