Elucidation of interface interactions between a dehydratase domain and an acyl carrier protein in cremimycin polyketide synthase

FEBS Letters, EarlyView.
In modular polyketide synthases, the dehydratase (DH) domain catalyzes the dehydration reaction of the β‐hydroxyacyl unit attached to the cognate acyl carrier protein (ACP) domain. However, it is unclear how DH interacts with ACP during the reaction. In this study, we identified DH–ACP interface residues, providing the first detailed insights into DH ...

Significance of indicator bacteria changes in an urban stream

Water Science and Technology, 1995
An urban coastal stream, above tidal reach, and three municipal wastewater treatment plant effluents were analyzed for fecal coliforms, fecal streptococci and enterococci to determine the effect of dechlorination on those bacterial populations. Analyses were conducted during low and high flow periods from stormwater inflow.

Functional variation among LPMOs revealed by the inhibitory effects of cyanide and buffer ions

FEBS Letters, EarlyView.
This study addresses the inhibition of lytic polysaccharide monooxygenases (LPMOs) by cyanide and explains how and why the magnitude of observed inhibitory effects depends on the way LPMO reactions are setup and on the type of LPMO. Enzymes known as lytic polysaccharide monooxygenases (LPMOs) are mono‐copper polysaccharide‐degrading peroxygenases that ...

Yeasts and filamentous fungi in bottled mineral water and tap water from municipal supplies

Brazilian Archives of Biology and Technology, 2007
The main objective of this study was to analyse the occurrence of yeasts and filamentous fungi in drinking water as well as to investigate their correlation with the indicator bacteria of faecal pollution.

Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones

FEBS Letters, EarlyView.
Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

Porphyrin-modified antimicrobial peptide indicators for detection of bacteria

Sensing and Bio-Sensing Research, 2016
AbstractThis study demonstrates the potential of porphyrin modified antimicrobial peptides for indication of bacterial targets on the basis of changes in the spectrophotometric characteristics of the construct. Detection is a result of changes in the structure of the antimicrobial peptide upon target binding. Those constructs comprised of peptides that

Structural and mechanistic basis for the regulation of the chloroplast signal recognition particle by (p)ppGpp

FEBS Letters, EarlyView.
LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.

The multiple roles of the NlpC_P60 peptidase family in mycobacteria – an underexplored target for antimicrobial drug discovery

FEBS Letters, EarlyView.
The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.

Microbiological quality and safety of goat’s milk from one farm

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2012
In recent years, the popularity of goat’s milk and goat’s milk products has been growing in the Czech Republic, especially for its low allergenic potential and good digestibility.
