The increasing number of genes encoding eukaryotic-type Ser/Thr protein kinases (ESTPKs) in prokaryotes, identified mostly due to genome-sequencing projects, suggests that these enzymes play an indispensable role in many bacterial species. Tadhg P. Begley, in Comprehensive Natural Products Chemistry, 1999, The toxic effects of UV irradiation on Streptomyces griseus, Streptomyces coelicolor, Staphylococcus epidermis, and E. coli can be reduced by a subsequent exposure to long wavelength UV light.126–128 This effect, called type III photoreactivation, is distinct from photoreactivation and is maximal at 314 nm, the λmax of the (6-4) photoproduct. Streptomyces coelicolor is a soil-dwelling Gram-positive bacterium that belongs to the genus Streptomyces. However, little is known about the utilization of the alternative nitrogen source ethanolamine. Streptomyces coelicolor contains three copies of genes for type III PKSs, which assemble 1,3,6,8-tetrahydroxynaphthalene. Under anaerobic conditions, NADH levels increase and Rex binds NADH which leads to inactivation of its repressor activity. In Streptomyces coelicolor and related species, glucose kinase is the key player of CCR, where it is independent of the PTS (van Wezel et al., 2007). Here, we have characterized the glycoproteome in Streptomyces coelicolor and shown that glycoproteins have diverse roles, including those related to solute binding, ABC transporters, and cell wall biosynthesis. In support of this hypothesis, we previously used S. coelicolor to measure DNaseI sensitivity in vivo and observed that transcriptionally active genes were located in regions of the chromosome with a more open nucleoid structure (McArthur & Bibb, 2006). Despite the DNA-binding motif of Rex homologs sharing significant conservation, the function of the genes regulated varies by organism (Ravcheev et al., 2012). An enzyme catalyzed conversion of the Dewar pyrimidinone back to two thymines has not been identified. In the presence of O2, Rex represses transcription of respiratory pathways by binding to the operator sequences of genes for high-affinity oxygen-dependent cytochrome bd oxidases (cydABCD), the proton-translocating NADH dehydrogenase (nuo operon), the haem biosynthesis operon (hemACD) and the rex gene itself [194]. Although hexanoyl-ACPs used in this study are not the native substrate of Gcs and Sco7671, these results support the hypothesis that Gcs and Sco7671 could interact with ACPs. 2013) and in S. coelicolor EsxA and EsxB are involved in sporulation (San Roman et al. In this novel polyketide synthesis pathway (Figure 6), the initial condensation is catalyzed by FabH, a β-ketoacyl carrier protein synthase III involved in the fatty acid biosynthesis.

A number of strains were related at the species level as they shared high DNA relatedness values (>80%). Rex senses changes of the NADH/NAD+ ratio in the cytosol and is active as repressor in the presence of NAD+ and inactivated by NADH. S. colombiensis was reduced to a synonym of S. lavendulae as it showed 83% DNA homology to S. lavendulae type strain. Streptomyces coelicolor A3(2) is the model species for the study of actinomycete genetics and biology, and a large array of genetic tools, including its genome sequence, is available to understand and manipulate the organism (Kieser et al., 2000; Bentley et al., 2002). The DNA-binding and NAD-sensing domains of Rex are widely conserved among 119 Rex orthologues identified in the phyla Firmicutes, Thermotogales, Actinobacteria, Chloroflexi, Deinococcus-Thermus, and Proteobacteria using a bioinformatic approach [200]. In accordance with a strong conservation of the DNA-binding domain, the Rex protein shows strong conservation and the structure has been solved in the presence and absence of NADH. Moreover, the specificity of Mtb PrcBA for N-acetyl tripeptide substrates is distinct from that of mammalian proteasomes [42].
