Expression of the bop gene cluster of Halobacterium halobium is induced by low oxygen tension and by light

Autor: Mary C. Betlach, R F Shand

Publikováno v: Journal of Bacteriology. 173:4692-4699

The bop gene cluster consists of at least three genes: bop (bacterio-opsin), brp (bacterio-opsin-related protein), and bat (bacterio-opsin activator). We have quantitated transcript levels from these genes in a wild-type and bacterioruberin-deficient

bop gene cluster expression in bacteriorhodopsin-overproducing mutants of Halobacterium halobium

Autor: R F Shand, Mary C. Betlach

mRNA levels from the bop (bacterio-opsin), brp (bacterio-opsin-related protein), and bat (bacterio-opsin activator) genes in wild-type Halobacterium halobium and two bacteriorhodopsin-overproducing mutants (ET1001 and II-7) were quantitated under con

Effects of Asp-96----Asn, Asp-85----Asn, and Arg-82----Gln single-site substitutions on the photocycle of bacteriorhodopsin

Autor: T E, Thorgeirsson, S J, Milder, L J, Miercke, M C, Betlach, R F, Shand, R M, Stroud, D S, Kliger

Publikováno v: Biochemistry. 30(38)

Bacteriorhodopsin (BR) with the single-site substitutions Arg-82----Gln (R82Q), Asp-85----Asn (D85N), and Asp-96----Asn (D96N) is studied with time-resolved absorption spectroscopy in the time regime from nanoseconds to seconds. Time-resolved spectra

Mutational analysis of the histidine operon promoter of Salmonella typhimurium

Autor: R F Shand, P H Blum, M S Urdea, S W Artz, Donald L. Holzschu

Publikováno v: Journal of bacteriology. 171(11)

We isolated a collection of 67 independent, spontaneous Salmonella typhimurium his operon promoter mutants with decreased his expression. The mutants were isolated by selecting for resistance to the toxic lactose analog o-nitrophenyl-beta-D-thiogalac

Correlation between histidine operon expression and guanosine 5'-diphosphate-3'-diphosphate levels during amino acid downshift in stringent and relaxed strains of Salmonella typhimurium

Autor: R D Mueller, R F Shand, S W Artz, Daniel L. Riggs, P H Blum

We have analyzed the correlation of attenuator-independent expression of the Salmonella typhimurium histidine operon in vivo with levels of the "alarmone" guanosine 5'-diphosphate 3'-diphosphate. Amino acid downshift caused by serine hydroxamate addi
