Novel mechanism of bacteriocin secretion and immunity carried out by lactococcal multidrug resistance proteins
(Amer Soc Biochemistry Molecular Biology Inc, Bethesda, 2003)
A natural isolate of Lactococcus lactis was shown to produce two narrow spectrum class II bacteriocins, designated LsbA and LsbB. The cognate genes are located on a 5.6-kb plasmid within a gene cluster specifying LmrB, an ...
Identification of quorum-sensing-regulated genes of Burkholderia cepacia
(Amer Soc Microbiology, Washington, 2003)
Quorum sensing is a regulatory mechanism (operating in response to cell density) which in gram-negative bacteria usually involves the production of N-acyl homoserine lactones (HSL). Quorum sensing in Burkholderia cepacia ...
Role of GacA, LasI, RhlI, ppk, PsrA, vfr and ClpXP in the regulation of the stationary-phase sigma factor rpoS/RpoS in Pseudomonas
(Springer-Verlag, New York, 2003)
RpoS is the stationary phase sigma factor responsible for increased transcription of a set of genes when bacterial cells enter stationary phase and under stress conditions. In Escherichia coli, RpoS expression is modulated ...
Regulation of rpoS gene expression in Pseudomonas: involvement of a TetR family regulator
(Amer Soc Microbiology, Washington, 2001)
The rpoS gene encodes the sigma factor which was identified in several gram-negative bacteria as a central regulator during stationary phase. rpoS gene regulation is known to respond to cell density, showing higher expression ...
Proizvodnja inducibilne ekstracelularne proteinaze pomoću prirodnog izolata Enterococcus faecalis BGPM3 / Natural isolate Enterococcus faecalis BGPM3 produces an inducible extracellular proteinase
(Srpsko biološko društvo, Beograd, i dr., 2000)
Enterococcus faecalis BGPM3 proizvodi proteinazu sposobnu da hidrolizuje ukupan kazein kao i frakcije αs1-, β-, i k-kazeina. Ova proteinaza, takođe, hidrolizuje želatin, ali ne deluje na denaturisani goveđi serum albumin ...
Regulation of the p-hydroxybenzoic acid hydroxylase gene (pobA) in plant-growth-promoting Pseudomonas putida WCS358
(Soc General Microbiology, Reading, 2001)
The regulation of the p-hydroxybenzoate hydroxylase gene (pobA) of Pseudomonas putida WC5358 involved in the catabolism of p-hydroxybenzoic acid (PHB) to the central intermediate protocatechuate was studied. Protocatechuic ...
Molekularna genetika autohtonih bakterija mlečne kiseline / Molecular genetics of autochthonous lactic acid bacteria
(Društvo genetičara Srbije, Beograd, 2000)
Autohtoni sojevi bakterija mlečne kiseline (BMK) su izolovane iz fermentisanih mlečnih proizvoda rađenih u domaćoj radinosti. Fermentisani mlečni proizvodi su sakupljani sa specifičnih ekoloških lokaliteta kao što su visoke ...
Karakterizacija prirodnog izolata Lactococcus lactis subsp. lactis BGIS29, proizvođača bakteriocina IS29 i proteinaze vezane za ćelijski zid / Characterisation of natural isolate Lactococcus lactis subsp. lactis BGIS29, a strain producing bacteriocin IS29 and cell wall-associated proteinase
(Srpsko biološko društvo, Beograd, i dr., 2001)
Soj Lactococcus lactis subsp. lactis BGIS29 je prirodni izolat iz sira proizvedenog u domaćinstvu koji proizvodi bakteriocin IS29 i proteinazu PI-tipa. Rezultati dobijeni biohemijskom karakterizacijom bakteriocina IS29 ...
The acetyl xylan esterase of Bacillus pumilus belongs to a family of esterases with broad substrate specificity
(Microbiology Soc, London, 2000)
The Bacillus pumilus gene encoding acetyl xylan esterase tare) was identified and characterized. The axe gene was expressed and the recombinant enzyme produced in Escherichia coli was purified and characterized. The ...
TetR family member PsrA directly binds the Pseudomonas rpoS and psrA promoters
(Amer Soc Microbiology, Washington, 2002)
We have previously described a Pseudomonas gene, psrA, which enhances transcription of the rpoS sigma factor gene at stationary phase. We present molecular data which demonstrate that in Pseudomonas putida PsrA binds ...
