Microbiologyopen. 2012 Sep;1(3):298-310. doi: 10.1002/mbo3.34. Epub 2012 Aug 14.

In bacteria, β-alanine is formed via the action of l-aspartate α-decarboxylase (PanD) which is one of the small class of pyruvoyl-dependent enzymes. The pyruvoyl cofactor in these enzymes is formed via the intramolecular rearrangement of a serine residue in...

PMID: 23170230
Microbiologyopen. 2012 Sep;1(3):311-25. doi: 10.1002/mbo3.32. Epub 2012 Aug 24.

The plant growth-promoting rhizobacterium Pseudomonas fluorescens WCS374r produces several iron-regulated metabolites, including the fluorescent siderophore pseudobactin (Psb374), salicylic acid (SA), and pseudomonine (Psm), a siderophore that contains a SA moiety. After purification of Psb374 from culture supernatant of WCS374r,...

The soluble pyocins S2 and S4 from Pseudomonas aeruginosa bind to the same FpvAI receptor.

PMID: 23170226
Microbiologyopen. 2012 Sep;1(3):268-75. doi: 10.1002/mbo3.27. Epub 2012 Jun 22.

Soluble (S-type) pyocins are Pseudomonas aeruginosa bacteriocins that kill nonimmune P. aeruginosa cells by gaining entry via a specific receptor, which, in the case of pyocin S2, is the siderophore pyoverdine receptor FpvAI, and in the case of pyocin...

Expression of a small (p)ppGpp synthetase, YwaC, in the (p)ppGpp(0) mutant of Bacillus subtilis triggers YvyD-dependent dimerization of ribosome.

PMID: 22950019
Microbiologyopen. 2012 Jun;1(2):115-34. doi: 10.1002/mbo3.16.

To elucidate the biological functions of small (p)ppGpp synthetases YjbM and YwaC of Bacillus subtilis, we constructed RIK1059 and RIK1066 strains carrying isopropyl-β-D-thiogalactopyranoside (IPTG) inducible yjbM and ywaC genes, respectively, in the ΔrelA ΔyjbM ΔywaC triple mutant background. While...

Importance of the latex-clearing protein (Lcp) for poly(cis-1,4-isoprene) rubber cleavage in Streptomyces sp. K30.

Yikmis M, Steinbüchel A.
PMID: 22950008
Microbiologyopen. 2012 Mar;1(1):13-24. doi: 10.1002/mbo3.3.

Streptomyces sp. strain K30 induces the formation of an extracellular Lcp (latex-clearing protein) during poly(cis-1,4-isoprene) degradation. To investigate the function of this enzyme in Streptomyces sp. strain K30, the lcp gene was disrupted. This was the first time that...

Debaryomyces hansenii strains differ in their production of flavor compounds in a cheese-surface model.

PMID: 22950022
Microbiologyopen. 2012 Jun;1(2):161-8. doi: 10.1002/mbo3.11.

Flavor production among 12 strains of Debaryomyces hansenii when grown on a simple cheese model mimicking a cheese surface was investigated by dynamic headspace sampling followed by gas chromatography-mass spectrometry. The present study confirmed that D. hansenii possess the...

Adaptation to potassium starvation of wild-type and K(+)-transport mutant (trk1,2) of Saccharomyces cerevisiae: 2-dimensional gel electrophoresis-based proteomic approach.

Microbiologyopen. 2012 Jun;1(2):182-93. doi: 10.1002/mbo3.23.

Saccharomyces cerevisiae wild-type (BY4741) and the corresponding mutant lacking the plasma membrane main potassium uptake systems (trk1,trk2) were used to analyze the consequences of K(+) starvation following a proteomic approach. In order to trigger high-affinity mode of potassium transport,...
