Nucleotide sequence analysis of the inversion termini located within IS3 elements α3β3 and β5α5 of Escherichia coli K-12
(Journal of Bacteriology, 1991)
This paper presents the first detailed structural analysis of termini of an inversion mediated by recombination between Escherichia coli native IS elements. The complete nucleotide sequence of the inversion termini in the ...
Characterization of the cell wall-bound proteinase of Lactobacillus casei HN14
(Applied and Environmental Microbiology, 1991)
Lactobacillus casei HN14, which was isolated from homemade cheese, produces an extracellular, cell wall-bound proteinase. The HN14 proteinase can be removed from the cell envelope by washing the cells in a Ca2+-free buffer. ...
Efficient transformation of Micromonospora melanosporea protoplasts by Streptomyces plasmid
(Springer-Verlag, 1991)
An efficient and relatively simple procedure for Micromonospora melanosporea protoplast preparation and transformation is described. Transformation of M. melanosporea protoplast by the Streptomyces plasmid pIJ702 was ...
Hybrid P(L)tl promoter with dual regulation control
(DNA and Cell Biology, 1991)
The newly constructed P(L)tl hybrid promoter is composed of the operator and promoter sequences of tac and the -35 to -135 region of the phage λ P(L) promoter, which contains the AT-rich block and the OL2 and OL3 segments. ...
Bacteriocin-producing strain of Lactococcus lactis subsp. diacitilactis S50
(Applied and Environmental Microbiology, 1991)
Lactococcus lactis subsp. diacitilactis S50 produces a bacteriocin, designated bacteriocin S50, which has a narrow antibacterial spectrum. It was active only against Lactococcus species, including a nisin producer exhibiting ...
