Gordonia polyisoprenivorans strain VH2, a potent rubber-degrading actinomycete, harbors two latex clearing proteins (Lcps), which are known to be essential for the microbial degradation of rubber. However, biochemical information on the exact role of this protein in the degradation of polyisoprene was lacking. In this study, the gene encoding Lcp1VH2 was heterologously expressed in strains of E...

Incubation of hen oviduct membranes with UDP-[14C]N-acetylglucosamine (GlcNAc) leads to the formation of four endogenously labeled lipids. One of these lipids has not previously been characterized. Based on its chromatographic behavior on SG-81 paper and DEAE-cellulose, it is a monophosphate diester. The oviduct lipid is extremely sensitive to mild acid hydrolysis and, based on a comparison wit...

ABSTRACT Although the fibrous plant material called Affenhaar from middle Eocene lignites of Geiseltal in Germany has been repeatedly studied for over 172 years, modern imaging and chemical analyses have enabled a deeper understanding its composition preservation within parent plant. Known English as “monkeyhair,” represents very rare case fossil laticifers, latex-bearing ducts plants. Here we ...

The present study is an extension of the cooperative kinematics (CK) approach (Bahar, I.; Erman, B.; Monnerie, L.Macromolecules 1992, 25, 6309), which has been demonstrated to give an efficient and realistic account of the mechanism of local relaxational processes in polyethylene (PE). In the present work, the effects of (i) departure from tetrahedral backbone geometry and (ii) differences in t...
