Antibodies to tyvelose exhibit multiple modes of interference with the epithelial niche of Trichinella spiralis.
Infection with the parasitic nematode Trichinella spiralis is initiated when the L1 larva invades host intestinal epithelial cells. Monoclonal antibodies specific for glycans on the larval surface and secreted glycoproteins protect the intestine against infection. Protective antibodies recognize tyvelose which caps the target glycan. In this study, we used an in vitro model of invasion to furth...
متن کاملHigh resolution x-ray structure of tyvelose epimerase from Salmonella typhi.
Tyvelose epimerase catalyzes the last step in the biosynthesis of tyvelose by converting CDP-d-paratose to CDP-d-tyvelose. This unusual 3,6-dideoxyhexose occurs in the O-antigens of some types of Gram-negative bacteria. Here we describe the cloning, protein purification, and high-resolution x-ray crystallographic analysis of tyvelose epimerase from Salmonella typhi complexed with CDP. The enzym...
متن کاملBiosynthesis of gold nanoparticles using streptomyces fulvissimus isolate
Objective(s): In recent years, the biosynthesis of gold nanoparticles has been the focus of interest because of their emerging application in a number of areas such as biomedicine. In the present study we report the extracellular biosynthesis of gold nanoparticles (AuNPs) by using a positive bacterium named Streptomyces fulvissimus isolate U from rice fields of Guilan Province, Iran.Materials a...
متن کاملBiosynthesis of Silver nanoparticles from Actinomycetes for therapeutic applications
Silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. Silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. A simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles. The present study aimed at the comparative study of silver nanopartic...
