Binding of Streptococcus oralis glyceraldehyde-3-phosphate dehydrogenase (GAPDH) to Porphyromonas gingivalis fimbriae was characterized via a biomolecular interaction analysis system. The interaction was specific, and the association constant value was 4.34 x 10(7) M(-1), suggesting that S. oralis GAPDH functions as a dominant receptor for P. gingivalis and contributes to P. gingivalis coloniza...

In an accompanying paper (l), it is shown that y-(p-arsenosophenyl)-n-butyrate activates the adenosine triphosphatase of both myosin and mitochondria, and several analogies between the properties of the active sites of these two energy transduction enzymes are discussed. Carbonyl cyanide p-chlorophenylhydrazone, which uncouples osidative phosphorylation at concentrations as low as lop7 &r (a), ...

dilated cardiomyopathy (dcm) is accompanied by myocytes and connective tissue changes. matrix metalloproteinases (mmps) play important roles in cardiac remodeling. it seems that the gelatinases (mmp-2 and mmp-9) are effective enzymes in cardiomyopathy. dilated cardiomyopathy was confirmed in 22 dogs (patient group) including 11 female and 11 male by clinical examination, auscultation, thoracic ...
