A) Map of the Streptomyces venezuelae dcw genomic region. Genes which have not been studied yet are shown in black (including the two genes of this study and excluding the mur genes). In order to highlight ftsZ we have shown the gene in red. The G refers to sepG and the X, F, E to murX, murF and murE genes. B) Phenotypic analyses of the strains constructed in this study. In all cases the cells on these plates were grown at 30 °C for a minimum of 4 days. Please, see Material and Method section for details about the growth determinations and culture conditions.
