The dimeric repressor SoxR binds cooperatively to the promoter(s) regulating expression of the sulfur oxidation (sox) operon of Pseudaminobacter salicylatoxidans KCT001
(SOC GENERAL MICROBIOLOGY, 2007-01)Sulfur oxidation in Pseudaminobacter salicylatoxidans KCT001 is rendered by the combined action of several enzymes encoded by a thiosulfate-inducible sox operon. In this study it has been conclusively demonstrated by ... -
DNA bending in the mycobacterial plasmid pAL5000 origin-RepB complex
(AMER SOC MICROBIOLOGY, 2007-12)Plasmid pAL5000 represents a family of relatively newly discovered cryptic plasmids in gram-positive Actinomycetes bacteria. The replication regions of these plasmids comprise a bicistronic operon, repA-repB, encoding two ... -
Modulation of DNA-binding activity of Mycobacterium tuberculosis HspR by chaperones
(SOC GENERAL MICROBIOLOGY, 2008-02)In Mycobacterium tuberculosis, hspR is the last gene of the dnaKJE operon. It encodes the repressor HspR, which regulates the expression from this operon by binding to a consensus upstream sequence known as HAIR (HspR-associated ... -
Cloning, characterization and expression analysis of nucleotide metabolism-related genes of mycobacteriophage L5
(BLACKWELL, 2008-03)The genomes of mycobacteriophages of the L5 family, which includes the lytic phage D29, contain several genes putatively linked to nucleotide- metabolizing functions. Two such genes, 48 and 50, encoding thymidylate synthase ... -
The Mycobacteriophage D29 Gene 65 Encodes an Early-Expressed Protein That Functions as a Structure-Specific Nuclease
(AMER SOC MICROBIOLOGY, 2009-02-01)The genomes of mycobacteriophages of the L5 family, which includes the lytic phage D29, contain several genes putatively linked to DNA synthesis. One such gene is 65, which encodes a protein belonging to the RecA/DnaB ...
