Microdiversification of a Pelagic Polynucleobacter Species Is Mainly Driven by Acquisition of Genomic Islands from a Partially Interspecific Gene Pool.

• Matthias Hoetzinger, Johanna Schmidt, Jitka Jezberová, Ulrike Koll, Martin W Hahn
• Applied and environmental microbiology
• 2017

Microdiversification of a planktonic freshwater bacterium was studied by comparing 37 Polynucleobacter asymbioticus strains obtained from three geographically separated sites in the Austrian Alps.… (More)

The v-myc-induced Q83 lipocalin is a siderocalin.

• Nicolas Coudevylle, Leonhard Geist, +4 authors Robert Konrat
• The Journal of biological chemistry
• 2010

Siderocalins are atypical lipocalins able to capture siderophores with high affinity. They contribute to the innate immune response by interfering with bacterial siderophore-mediated iron uptake but… (More)

Polynucleobacter wuianus sp. nov., a free-living freshwater bacterium affiliated with the cryptic species complex PnecC.

• Martin W Hahn, Lesley R Huymann, Ulrike Koll, Johanna Schmidt, Elke Lang, Matthias Hoetzinger
• International journal of systematic and…
• 2017

Strain QLW-P1FAT50C-4T, isolated from a shallow, acidic freshwater pond located in the Austrian Alps at an altitude of 1300 m, was characterized by investigation of phenotypic, chemotaxonomic and… (More)

Lipocalin Q83 reveals a dual ligand binding mode with potential implications for the functions of siderocalins.

• Nicolas Coudevylle, Matthias Hoetzinger, +4 authors Robert Konrat
• Biochemistry
• 2011

Siderocalins are particular lipocalins that participate in the innate immune response by interfering with bacterial siderophore-mediated iron uptake. Additionally, siderocalins are involved in… (More)

Siderocalin Q83 exhibits differential slow dynamics upon ligand binding

• Nicolas Coudevylle, Leonhard Geist, Matthias Hoetzinger, Martin Tollinger, Robert Konrat
• Journal of biomolecular NMR
• 2011

Siderocalin Q83 is a small soluble protein that has the ability to bind two different ligands (enterobactin and arachidonic acid) simultaneously in two distinct binding sites. Here we report that Q83… (More)

Ligand binding properties of the siderocalins NGAL and Q83

• Matthias Hoetzinger
• 2011

NGAL ist ein 178 Aminosauren groses, menschliches Protein und gehort zur Familie der Siderocaline. Es kommt in sekretorischen Vesikeln von Granulozyten vor. Siderocaline sind eine Unterklasse der… (More)

Polynucleobacter paneuropaeus sp. nov., characterized by six strains isolated from freshwater lakes located along a 3000 km north-south cross-section across Europe.

• Matthias Hoetzinger, Johanna Schmidt, Alexandra Jeanne Pitt, Ulrike Koll, Elke Lang, Martin W Hahn
• International journal of systematic and…
• 2019

Six Polynucleobacter (Burkholderiaceae, Betaproteobacteria) strains isolated from different freshwater lakes located across Europe were taxonomically investigated. Phylogenetic analyses based on 16S… (More)

Genomic divergence and cohesion in a species of pelagic freshwater bacteria

• Matthias Hoetzinger, Martin W Hahn
• BMC Genomics
• 2017

BackgroundIn many prokaryotic genera a clustered phylogeny is observed, akin to the occurrence of species in sexually reproducing organisms. For some taxa, homologous recombination has been invoked… (More)
