ABP-dHC-cecropin A is a linear cationic peptide that exhibits antimicrobial properties. To explore a new approach for expression of ABP-dHC-cecropin A using the methylotrophic yeast Pichia pastoris, we cloned the ABP-dHC-cecropin A gene into the vector pPICZαA. The SacI-linearized plasmid pPICZαA-ABP-dHC-cecropin A was then transformed into P. pastoris(More)
The antimicrobial peptide ABP-dHC-cecropin A is a small cationic peptide with potent activity against a wide range of bacterial species. Evidence of antifungal activity has also been suggested; however, evaluation of this peptide has been limited due to the low expression of cecropin proteins in Escherichia coli. To improve the expression level of(More)
Nucleoside diphosphate kinases (NDPKs) are multifunctional proteins that regulate a variety of eukaryotic cellular activities, including cell proliferation, development, and differentiation. NDPK2 regulates the expression of antioxidant genes in plants. In a previous study, the Arabidopsis thaliana NDPK2 gene (AtNDPK2) was found to be associated with(More)
The increasing resistance of bacteria and fungi to currently available antibiotics is a major concern worldwide, leading to enormous effort to develop novel antibiotics with new modes of action.We recently reported that ABP-dHC-cecropin A exhibited strong antibacterial and antifungal activity, making it a candidate antibiotic substitute. In this study,(More)
