Phenotypic plasticity leads to incongruence between morphology-based taxonomy and genetic differentiation in western Palaearctic tortoises (Testudo graeca complex; Testudines, Testudinidae)
All studied populations of the T. graeca complex are conspecific under the Biological Species Concept and there is major incongruence between mtDNA clades and morphologically defined taxa. Expand
Diversity of the Southeast Asian leaf turtle genus Cyclemys: how many leaves on its tree of life?
In the present study, we use mtDNA sequence data (cyt b gene) in combination with nuclear DNA sequences (C‐mos, Rag2 genes, R35 intron), nuclear genomic fingerprints (ISSR) and morphological data toExpand
A rangewide phylogeography of Hermann's tortoise, Testudo hermanni (Reptilia: Testudines: Testudinidae): implications for taxonomy
Hermann's tortoise (Testudo hermanni), the best‐known western Palaearctic tortoise species, has a rare natural distribution pattern comprising the Mediterranean areas of the Iberian, Apennine, andExpand
The world’s economically most important chelonians represent a diverse species complex (Testudines: Trionychidae: Pelodiscus)
The findings provide evidence for the existence of at least seven distinct genetic lineages and suggest interbreeding in commercial turtle farms, and reveal the need for a new assessment of the conservation status of Pelodiscus. Expand
Population structures of syntopic Emys orbicularis and Mauremys rivulata in western Turkey
Data on body size, population density, sex ratio, age, and sexual maturity are presented for a syntopic population of Emys orbicularis and Mauremys rivulata from Cukurkoy, western Turkey. 49 E.Expand
Total Conversion of Bifunctional Catalase-Peroxidase (KatG) to Monofunctional Peroxidase by Exchange of a Conserved Distal Side Tyrosine*
For the first time a clear transition of compound I to an oxoferryl-like compound II with peaks at 418, 530, and 558 nm was monitored when one-electron donors were added to compound I. Expand
A new species of karst dwelling Cyrtodactylus (Squamata: Gekkonidae) from northwestern Laos
A new species of karst dwelling Cyrtodactylus (Squamata: Gekkonidae) from northwestern Laos is described. Expand
Protein-based radicals in the catalase-peroxidase of synechocystis PCC6803: a multifrequency EPR investigation of wild-type and variants on the environment of the heme active site.
Catalase-peroxidases are bifunctional heme enzymes with a high structural homology to peroxidases from prokaryotic origin and a catalatic activity comparable to monofunctional catalases. These uniqueExpand
Distal site aspartate is essential in the catalase activity of catalase-peroxidases.
The reactivity of compound I toward aromatic one-electron donors was enhanced in the Asp152 variants compared with the wild-type protein, whereas the reactivity toward hydrogen peroxide was dramatically decreased. Expand
A Stable Bacterial Peroxidase with Novel Halogenating Activity and an Autocatalytically Linked Heme Prosthetic Group*
It is shown that post-translational autocatalytic peroxide-driven heme modification is found in prokaryotic and eukaryotic halogenating peroxidases and for the first time, an ancestral bacterial hemeperoxidase is shown to possess a very high bromide oxidation activity (besides conventional peroxIDase activity).
