Striking similarities between vaccinia virus hemagglutinin (VVHA) and proteins belonging to the Ig superfamily clearly indicate that VVHA, a 315-amino acid glycoprotein expressed on the surface of the infected cells, is a novel viral protein that can be added to the expanding list of the Ig superfamily. Its deduced amino acid sequence contains one Ig-like(More)
NZ2114 is a promising candidate for therapeutic application owing to its potent activity to Staphylococcus aureus. Our objective was to identify NZ2114 derivatives with improved activity through substitution of His16 and His18 with residues Arginine and Lysine. Eight mutants were designed and expressed in Pichia pastoris X-33 via pPICZαA. Five of them(More)
Carbon nanomaterials in the form of paper sheets have been used as platforms to achieve multifunctionality. Combined with electrochemical deposition, room temperature synthesis of magnetic Ni coatings on individual carbon nanofibers (CNF) and/or carbon nanotubes (CNT) has been realized through solution penetration and ion diffusion. In addition to(More)
NZ17074 (N1), an arenicin-3 derivative isolated from the lugworm, has potent antibacterial activity and is cytotoxic. To reduce its cytotoxicity, seven N1 analogues with different structures were designed by changing their disulfide bonds, hydrophobicity, or charge. The "rocket" analogue-N2 and the "kite" analogue-N6 have potent activity and showed lower(More)
This work is the first to report the antibacterial characteristics and antibacterial mechanisms of MP1102, which is a variant of NZ2114, against pathogenic Clostridium perfringens. MP1102 exhibited strong antimicrobial activity against C. perfringens strains CVCC 61, CVCC 1163, and CVCC 2032 at a low minimal inhibitory concentration (MIC) of 0.91 μM. MP1102(More)
NZ2114 is a promising candidate for therapeutic application owing to potent activity to gram-positive bacterium such as Streptococcus pneumoniae and Staphylococcus aureus. This work is the first report to describe the in vitro and in vivo antibacterial characteristics of NZ2114 against Streptococcus suis. It exhibited strong antimicrobial activity against(More)
Lactoferrin (Lf), a multifunctional glycoprotein, is an important antimicrobial and immune regulatory protein present in neutrophils and most exocrine secretions of mammals. Lactoferricin (Lfcin) is located in the N-terminal region of this protein. In this review, the current state of research into Lf and Lfcin in China is described. Searching with HistCite(More)
Peanut meal (PM) is limited in practical use (feed or food) from imbalance of amino acid profile and denaturation of protein. Fermentation was used to promote its nutritional and functional properties by single-factor experiments and orthogonal experiments. Results showed that the nutritional properties of fermented peanut meal (crude protein content, dry(More)
Bovine lactoferricin (LfcinB) has potent antibacterial, antifungal and antiparasitic activities but is also hemolytic. Our objective was to identify LfcinB17-31 derivatives with reduced hemolysis and improved antimicrobial activity via substituting Cys3, Arg4, Gln7, Met10, and Gly14 with more hydrophobic residues. Two peptides, Lfcin4 and Lfcin5, showed(More)
