Structural and functional analysis of the S-layer protein crystallisation domain of Lactobacillus acidophilus ATCC 4356 : evidence for protein : protein interaction of two subdomains

The structure of the crystallisation domain, SAN, of the S A-protein of Lactobacillus acidophilus ATCC 4356 was analysed by insertion and deletion mutagenesis, and by proteolytic treatment. Mutant S A-protein synthesised in Escherichia coli with 7-13 amino acid insertions near the N terminus or within regions of sequence variation in SAN (amino...

A hepatocyte nuclear factor-3 site in the fibrinogen beta promoter is important for interleukin 6-induced expression, and its activity is influenced by the adjacent -148C/T polymorphism

An elevated plasma fibrinogen level is an independent risk factor for cardiovascular disease. Therefore, an understanding of the regulation of fibrinogen expression is important. Inflammation and genetic variation of the fibrinogen beta gene regulate plasma fibrinogen levels, and there are indications that inflammation and genetic variation...
