Differential fiu–lacZ fusion regulation linked to Escherichia coli colony development
(Blackwell: Molecular Microbiology, 1999-07)
Colonies of strains carrying a stable λplacMu15 translational fusion displayed sharply defined intense staining at the centre on Xgal medium. The fusion was in fiu (ferric ion uptake), encoding an iron-regulated outer ...
Identification and characterization of the nudix hydrolase from the Archaeon, Methanococcus jannaschii, as a highly specific ADP-ribose pyrophosphatase
(The American Society for Biochemistry and Molecular Biology: Journal of Biological Chemistry, 1998-08-14)
The MJ1149 gene from the Archaeon, Methanococcus jannaschii, has been cloned and expressed in Escherichia coli. The 19-kDa protein containing the Nudix box, GX5EX7REUXEEXGU, has been purified and identified as a highly ...
Escherichia coli orf17 codes for a nucleoside triphosphate pyrophosphohydrolase member of the MutT family of proteins
(The American Society for Biochemistry and Molecular Biology: Journal of Biological Chemistry, 1996-10-04)
The product of the Escherichia coli orf17 gene is a novel nucleoside triphosphate pyrophosphohydrolase with a preference for dATP over the other canonical (deoxy)nucleoside triphosphates, and it catalyzes the hydrolysis ...
Apparent cytochrome gene dose effects in F-lac and F-gal heterogenotes of Escherichia coli.
(Elsevier: Archives of Biochemistry and Biophysics, 1972-06)
The levels of b- and c-type cytochromes and cytochromes a1 and a2 are elevated in a partial diploid strain of E. coli carrying the F2-gal episome under a variety of different growth conditions. Only the levels of b- and ...
