The purified AFPME with a yield of 522% was resolved as one band

The purified AFPME with a yield of 52.2% was resolved as one band with a molecular mass of c. 40 kDa by SDS-PAGE. Optimal activity of the enzyme occurred at a temperature of 55 °C and a pH of 4.8. Epigallocatechin gallate (EGCG) strongly inhibited the activity of recombinant AFPME. The molecular docking analysis indicated that EGCG could form hydrogen

bonds and π–π interactions with some amino acid residues in the active site of AFPME. Our studies provide a novel strategy for the control of the plant invasion of A. flavus. “
“Plasmodium falciparum (Pf) apicoplast Y-27632 order is an essential organelle harbouring a ~35-kb circular genome. Prokaryotic nature of this organelle and its components makes it an attractive therapeutic

target. The single-stranded DNA-binding protein (SSB) and multidomain protein PfPrex are important apicoplast replication proteins. However, regulation of these proteins through protein–protein interaction remains Cilomilast clinical trial largely unknown. Here, we report that P. falciparum single-stranded DNA-binding protein (PfSSB) interacts with PfPrex helicase and modulates its activity. N-terminal domain of PfSSB is involved in this interaction, whereas C-terminal domain plays a pivotal role in the modulation of helicase activity. These results further, to our knowledge, understand apicoplast DNA replication. “
“We developed a multiplex PCR to detect the presence of methicillin- (mecA), cadmium/zinc-(czrC) and antiseptic-resistant (qacA/B) staphylococci and to identify Panton–Valentine leukocidin (PVL)-positive and -negative Staphylococcus aureus and coagulase-negative staphylococci (CoNS) from infected and healthy eyes. The assay was validated on 177 staphylococci comprising of 55 each of S. aureus and CoNS isolated from infected eyes and five S. aureus and 62 CoNS isolated from healthy eyes and nine direct ocular samples. Nine direct ocular samples for in situ testing consisted of corneal scrapings (4), conjunctiva swabs DOK2 (2) and others (3). Multiplex

PCR result was correlated with genotype data obtained with single PCR and dot-blot assay. The control strains that were positive in multiplex PCR for 16S rRNA, nuc, mecA, pvl, czrC and qacA/B genes were also positive in the dot-blot assay. The specificity of amplified genes obtained with reference strains was further confirmed by DNA sequencing. The single step-hexaplex PCR method can be used for rapid detection of mecA, nuc, pvl, czrC and qacA/B genes in staphylococci with simultaneous identification of PVL-positive and -negative S. aureus and CoNS from a variety of ocular samples. “
“The transcription factors ChAP1 and Skn7 of the maize pathogen Cochliobolus heterostrophus are orthologs of Yap1 and Skn7 in yeast, where they are predicted to work together in a complex. Previous work showed that in C. heterostrophus, as in yeast, ChAP1 accumulates in the nucleus in response to reactive oxygen species (ROS).
