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 ...
Characterization of melanin-overproducing transposon mutants of Pseudomonas putida F6
(Oxford Univ Press, Oxford, 2009)
Two melanin-overproducing Pseudomonas putida F6 mutants were generated using transposon (Tn5) mutagenesis. Mutants were disrupted in a transcriptional regulator (TR) and a homogentisate 1,2-dioxygenase (HDO) gene. Colonies ...
Ekstracelularne proteinaze prirodnih izolata stafilokoka / Extracellular proteinases in natural isolates of Staphylococci
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2005)
U ovom radu su detaljnije biohemijski okarakterisane proteinaze prirodnih izolata Staphylococcus sp. F22, F86, M104, S2007 i S2105. Utvrđeno je da se radi o proteinazama relativno male molekulske mase (od 20 do 32 kDa) ...
The Rest Repression of the Neurosecretory Phenotype Is Negatively Modulated by BHC80, a Protein of the BRAF/HDAC Complex
(Soc Neuroscience, Washington, 2009)
Expression of neurosecretion by nerve cells requires the levels of the transcription repressor element-1 silencing transcription factor (REST) to be very low. However, when high-REST clones of PC12 cells, defective of ...
Karakterizacija i antimikrobna aktivnost prirodnog izolata Lactococcus lactis subsp. lactis BGSM1-19 / Characterization and antimicrobial activity of natural isolate Lactococcus lactis subsp. lactis BGSM1-19
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2007)
Soj Lactococcus lactis subsp. lactis BGSM1-19, izolovan iz sira tradicionalno proizvedenog u domaćinstvu, sintetiše dva bakteriocina: bakteriocin BacSMa koji pripada grupi laktokokcina B i bakteriocin BacSMb koji pokazuje ...
Trans-aktivacija humanog SOX3 promotora MAZ proteinom u NT2/D1 ćelijama / Trans-activation of the human SOX3 promoter by MAZ in NT2/D1 cells
(Srpsko biološko društvo, Beograd, i dr., 2008)
U ovom radu proučavana je uloga tri visoko konzervisana potencijalna mesta vezivanja za "Myc-associated zinc finger protein" (MAZ) u regulaciji ekspresije humanog SOX3 gena. Eseji izmenjene elektroforetske pokretljivosti ...
Humani SOX18 gen - ekspresiona analiza i karakterizacija uzvodnog regulatornog regiona / The human SOX18 gene: Expression analysis and characterization of its 5’ flanking region
(Srpsko biološko društvo, Beograd, i dr., 2007)
Cilj ovog rada bio je uspostavljanje odgovarajućeg in vitro model sistema za proučavanje transkripcione regulacije ekspresije humanog SOX18 gena. U ovom radu prikazana je ekspresiona analiza SOX18 gena u permanentnim ...
Aminoglycoside resistance genes sgm and kgmB protect bacterial but not yeast small ribosomal subunits in vitro despite high conservation of the rRNA A-site
(Elsevier Science Bv, Amsterdam, 2008)
The aminoglycoside resistance genes sgm from Micromonospora zionensis and kgmB from Streptomyces tenebrarius were cloned into a yeast expression vector to test whether the encoded prokaryotic methylases can modify the 18S ...
Rec2 interplay with both Brh2 and Rad51 balances recombinational repair in Ustilago maydis
(Amer Soc Microbiology, Washington, 2006)
Rec2 is the single Rad51 paralog in Ustilago maydis. Here, we find that Rec2 is required for radiation-induced Rad51 nuclear focus formation but that Rec2 foci form independently of Rad51 and Brh2. Brh2 foci also form in ...
Preliminary characterization of lactic acid bacteria isolated from Zlatar cheese
(Wiley, Hoboken, 2007)
Aims: Isolation, characterization and identification of lactic acid bacteria (LAB) from artisanal Zlatar cheese during the ripening process and selection of strains with good technological characteristics. Methods and ...
