inhibitory specificity change of the ovomucoid third domain of the silver pheasant upon introduction of an engineered cys14-cys39 bond.the ovomucoid third domain from silver pheasant (omsvp3), a typical kazal-type inhibitor, strongly inhibits different serine proteases of various specificities, i.e., chymotrypsin, streptomyces griseus protease, subtilisin, and elastase. structural studies have suggested that conformational flexibility in the reactive site loop of the free inhibitor may be related to broad specificity of the ovomucoid. on the basis of the structural homology between omsvp3 and ascidian trypsin inhibitor (ati), w ...200312614146
structural and functional study of an anemonia elastase inhibitor, a "nonclassical" kazal-type inhibitor from anemonia sulcata.anemonia elastase inhibitor (aei) is a "nonclassical" kazal-type elastase inhibitor from anemonia sulcata. unlike many nonclassical inhibitors, aei does not have a cystine-stabilized alpha-helical (csh) motif in the sequence. we chemically synthesized aei and determined its three-dimensional solution structure by two-dimensional nmr spectroscopy. the resulting structure of aei was characterized by a central alpha-helix and a three-stranded antiparallel beta-sheet of a typical kazal-type inhibito ...200516008348

emergence of genetic diversity and multi-drug resistant campylobacter jejuni from wild birds in beijing, china.campylobacter jejuni (c. jejuni) is considered as an opportunistic zoonotic pathogen that may cause gastroenteritis in humans and other animals. wild birds may be as potential vectors of c. jejuni around urban and suburban areas. here, 520 samples were collected from 33 wild bird species in urban and suburban areas, beijing. in total 57 c. jejuni were isolated from seven species. it was found that nineteen (33.33%, 19/57) isolates were resistant to at least one of 11 antibiotics, especially stre ...201931736887
karyotypic evolution in the galliformes: an examination of the process of karyotypic evolution by comparison of the molecular cytogenetic findings with the molecular phylogeny.to define the process of karyotypic evolution in the galliformes on a molecular basis, we conducted genome-wide comparative chromosome painting for eight species, i.e. silver pheasant (lophura nycthemera), lady amherst's pheasant (chrysolophus amherstiae), ring-necked pheasant (phasianus colchicus), turkey (meleagris gallopavo), western capercaillie (tetrao urogallus), chinese bamboo-partridge (bambusicola thoracica) and common peafowl (pavo cristatus) of the phasianidae, and plain chachalaca (o ...200415218250

increasing the hydrolysis constant of the reactive site upon introduction of an engineered cys(14) cys(39) bond into the ovomucoid third domain from silver pheasant.p14c/n39c is the disulfide variant of the ovomucoid third domain from silver pheasant (omsvp3) introducing an engineered cys(14) cys(39) bond near the reactive site on the basis of the sequence homology between omsvp3 and ascidian trypsin inhibitor. this variant exhibits a narrower inhibitory specificity. we have examined the effects of introducing a cys(14) cys(39) bond into the flexible n-terminal loop of omsvp3 on the thermodynamics of the reactive site peptide bond hydrolysis, as well as t ...201121644249
replacement of native by non-native animal communities assisted by human introduction and management on isla victoria, nahuel huapi national park.one of the possible consequences of biological invasions is the decrease of native species abundances or their replacement by non-native species. in andean patagonia, southern argentina and chile, many non-native animals have been introduced and are currently spreading. on isla victoria, nahuel huapi national park, many non-native vertebrates were introduced ca. 1937. records indicate that several native vertebrates were present before these species were introduced. we hypothesize that seven dec ...201526623176

[habitat selection of four sympatric pheasants in guanshan national nature reserve, jiangxi, china].habitat selection of four sympatric pheasants (syrmaticus ellioti, lophura nycthemera, pucrasia macrolopha and bumbusicola thoracica) was studied in guanshan national nature reserve, jiangxi, china from october 2009 to november 2010. we measured seventeen ecological factors across 388 sites used by the four pheasants by direct observation in six transects. the results show that the pheasants preferred broad-leaved forest and coniferous forest and a sunny or semi-shaded slope. there were differen ...201222467392
phylogeography of silver pheasant (lophura nycthemera l.) across china: aggregate effects of refugia, introgression and riverine barriers.the role of pleistocene glacial cycles in forming the contemporary genetic structure of organisms has been well studied in china with a particular focus on the tibetan plateau. however, china has a complex topography and diversity of local climates, and how glacial cycles may have shaped the subtropical and tropical biota of the region remains mostly unaddressed. to investigate the factors that affected the phylogeography and population history of a widely distributed and nondeciduous forest spe ...201323692215
