there are specific forms of mural paintings in some iranian churches that are different from other usual wall paintings in materials, methods as well as implementation techniques. unfortunately, these mural paintings are not studied until now. the aim of this paper is the identification of history of development, and used materials and techniques in these historic paintings by field and literat...

VanK is the fourth member of the ubiquitous major facilitator superfamily of transport proteins to be identified that, together with PcaK, BenK, and MucK, contributes to aromatic catabolism in Acinetobacter sp. strain ADP1. VanK and PcaK have overlapping specificity for p-hydroxybenzoate and, most clearly, for protocatechuate: inactivation of both proteins severely impairs growth with protocate...

Genome-wide data mining indicated that six genes (ncgl1031, ncgl2302, ncgl2325, ncgl2326, ncgl2922 and ncgl2953) encoding putative transport proteins are involved in uptake of various aromatic compounds that are further degraded through the beta-ketoadipate, gentisate and resorcinol pathways in Corynebacterium glutamicum. The gentisate (GenK/NCgl2922) and vanillate (VanK/NCgl2302) transporters ...

Polydnaviruses are mutualists of their parasitoid wasps and express genes in immune cells of their Lepidopteran hosts. Polydnaviral genomes carry multiple copies of viral ankyrins or vankyrins. Vankyrin proteins are homologous to IκB proteins, but lack sequences for regulated degradation. We tested if Ichnoviral Vankyrins differentially impede Toll-NF-κB-dependent hematopoietic and immune signa...

Vancomycin is the front-line therapy for treating problematic infections caused by methicillin-resistant Staphylococcus aureus (MRSA), and the spread of vancomycin resistance is an acute problem. Vancomycin blocks cross-linking between peptidoglycan intermediates by binding to the D-Ala-D-Ala termini of bacterial cell wall precursors, which are the substrate of transglycosylase/transpeptidase. ...

INTRODUCTION At the invitation of the Dean and Chapter of Rochester Cathedral, the Canterbury Archaeological Trust carried out an excavation within the Lay cemetery of the Cathedral during April and May 1990. This project, funded by the Cathedral authorities, was undertaken before work began on the consolidation of the foundations of the Chair Store, which is situated between the west side of t...
