NZ2114, a new variant of plectasin, was overexpressed in Pichia pastoris X-33 via pPICZαA for the first time. The total secreted protein of fermentation supernatant reached 2,390 mg/l (29 °C) and 2,310 mg/l (25 °C), and the recombinant NZ2114 (rNZ2114) reached 860 mg/l (29 °C) and 1,309 mg/l (25 °C) at 96 h induction in a 5-l fermentor, respectively.The(More)
A novel specifically targeted antimicrobial peptide (STAMP) that was especially effective against methicillin-resistant Staphylococcus aureus (MRSA) was designed by fusing the AgrD1 pheromone to the N-terminal end of plectasin. This STAMP was named Agplectasin, and its gene was synthesized and expressed in Pichia pastoris X-33 via pPICZαA. The highest(More)
The rapid growth of scientific literature calls for automatic and efficient ways to facilitate extracting experimental data on protein phosphorylation. Such information is of great value for biologists in studying cellular processes and diseases such as cancer and diabetes. Existing approaches like RLIMS-P are mainly rule based. The performance lays much(More)
To detect the soybean allergen P34 (Gly m Bd 30K) from soybean products, the full-length cDNA sequence of P34 was synthesized and inserted into the prokaryotic expression vector pET-28a. The P34 protein was expressed in Escherichia coli BL21 (DE3) as an inclusion body under the induction of 0.8 mmol/L isopropyl β-d-1-thiogalactopyranoside. After(More)
The tri-hybrid peptide-LHP7 has the potent activity against Gram-positive and Gram-negative as well as fungi, but its mechanism of action has remained elusive. The effluences of LHP7 on the Staphylococcus aureus cell membrane and targets of intracellular action were investigated. LHP7 exhibited an inhibitory effect on the S. aureus growth, similar to those(More)
Enterocin A is a classic IIa bacteriocin isolated firstly from Enterococcus faecium CTC492 with selective antimicrobial activity against Listeria strains. However, the application of enterocin A as an anti-Listeria agent has been limited due to its very low native yield. The present work describes high production of enterocin A through codon optimization(More)
A novel antimicrobial peptide MP1106 was designed based on the parental peptide plectasin with four mutational sites and a high level of expression in Pichia pastoris X-33 via the pPICZαA plasmid was achieved. The concentration of total secreted protein in the fermented supernatant was 2.134 g/l (29 °C), and the concentration of recombinant MP1106 (rMP1106)(More)
Currently, more antimicrobial drug candidates are urgently needed to combat the rise in drug-resistance among pathogenic microbes. A new antimicrobial peptide, MP1102, a variant of NZ2114, was designed, evaluated, and overexpressed in Pichia pastoris. The total secreted protein in cultures reached 695 mg/l, and the concentration of the recombinant MP1102(More)
Surgery, chemotherapy, and radiotherapy have presented with the ability of killing tumor cells, as well as damaging the immune function, which can be corrected by the immunotherapy. The purpose of this perspective cohort study was to evaluate the efficacy of postoperative immunotherapies of tumor lysate-loaded dendritic cells (DC), in vitro DC-activated T(More)
