Cardiac to cancer: connecting connexins to clinical opportunity.

abstract：:Treatment of yeast phosphoglycerate kinase (PGK) with trypsin results in a fourfold increase in the Vmax of this enzyme, without affecting the Km. This activation is shown to be due to the removal of the C-terminal lysine residue. The C-terminal sequence folds back over the N-terminal domain and contacts the extreme N...
