Comparative impact of cadmium on two phenanthrene-degrading bacteria isolated from cadmium and phenanthrene co-contaminated soil in China.
Alcaligenes faecalis strain J08 and Brevundimonas sp. strain X08 were isolated from soils co-contaminated by cadmium (Cd) and polycyclic aromatic hydrocarbons (PAHs) in Northeast China. The twoExpand
Resistance mutations of Pro197, Asp376 and Trp574 in the acetohydroxyacid synthase (AHAS) affect pigments, growths, and competitiveness of Descurainia sophia L
The results indicated the R plants carrying Pro197Leu or Pro197His or Asp376Glu or Trp574Leu displayed stronger competitiveness than S plants, and these resistance mutation have no obvious adverse effects on the pigments, growths, relative growth rates, leaf area ratio, and net assimilation rate of R plants.

Effects of resistance mutations of Pro197, Asp376 and Trp574 on the characteristics of acetohydroxyacid synthase (AHAS) isozymes.
The molecular docking results indicated that these resistance mutations altered AHAS binding affinity for tribenuron-methyl by reducing the hydrogen bonds and changing hydrophobic interactions, but the mutations did not necessarily affect the biosynthesis of BCAAs in plants. Expand
Isolation and Purification of Antioxidant and ACE‐Inhibitory Peptides from Yak (Bos grunniens) Skin
Yak (Bos grunniens) is a kind of cattle which can survive on Tibetan plateau. In addition, yak skin is an unused resource during production of meat. In this research, the potential angiotensinExpand
Crystal structures of apo‐DszC and FMN‐bound DszC from Rhodococcus erythropolis D‐1
The first crystal structure of FMN‐bound DszC is determined, and it is found that two distinct conformations occur in the loop region (residues 131–142) adjacent to the active site. Expand
A novel mode of ferric ion coordination by the periplasmic ferric ion-binding subunit FbpA of an ABC-type iron transporter from Thermus thermophilus HB8.
Crystal structures of FbpA, the periplasmic ferric ion-binding protein of an iron-uptake ABC transporter, from Thermus thermophilus HB8 (TtFbpA) have been solved in apo and ferric ion-bound forms atExpand
Investigation of glyphosate resistance levels and target-site based resistance (TSR) mechanisms in Conyza canadensis (L.) from apple orchards around areas of Bohai seas and Loess Plateau in China.
The resistance levels to glyphosate and target-site based resistance mechanisms in susceptible (S) and resistant (R) Conyza canadensis (L.) populations, which were collected from apple orchardsExpand
Human CTP:phosphoethanolamine cytidylyltransferase: enzymatic properties and unequal catalytic roles of CTP-binding motifs in two cytidylyltransferase domains.
The results suggest that the N-terminal CT domain of hECT contributes to its catalytic reaction, but C-terminAL CT domain does not, and that the histidines, especially the first histidine, in the CTP-binding motif HxGH in the ECT domain were critical for its catalytical activity in vitro. Expand
A novel six-coordinated ferric ion binding mode of TtFbpA
Iron is an essential element for the growth and survival of nearly all living organisms. However, it is difficult for most organisms to get enough iron from the environment, because of the extremelyExpand
Investigation of hydrolysis conditions and properties on protein hydrolysates from flatfish skin
Response surface method (RSM), based on Box-Behnken design, was used to optimize the enzymatic hydrolysis conditions of flatfish skin protein hydrolysates (FSPH). Among the tested proteases, theExpand
