Emission of Isocyanates from Pur-adhesives. Time Course of Emission from Curing Pur-adhesive

The time course of isocyanate emission from curing PUR-adhesives was studied in an emission test chamber. The adhesives under investigation were commercial products for fixing of textile floor coverings and based on methylene bisphenyl diisocyanate (MDI). Influence of the curing mechanism was studied by comparing the emission curves of one-component adhesive (OCA) and two-component adhesive (TC...

Functional dissection of the Bacillus subtilis pur operator site.

Bacillus subtilis PurR represses transcription of several genes involved in purine synthesis, metabolism, and transport and cofactor synthesis. PurR binds specifically to DNAs containing an inverted repeat of a 14-nucleotide "PurBox" located in the upstream control regions of genes in the PurR regulon. Further biochemical investigation of the interaction of PurR with a series of shortened upstr...
