The abdominal aortic aneurysm (AAA) wall represents an extreme example of arterial remodeling with disturbed elastin, collagen and proteoglycan metabolism. The aim of this study was to evaluate enzymes involved in the degradation of glycosaminoglycan chains and core proteins of
Trp-999 is a key residue for the action of beta-galactosidases (Escherichia coli). Several site specific substitutions (Phe, Gly, Tyr, Leu) for Trp-999 were made. Each substitution caused greatly decreased affinities for substrates and inhibitors that bind in the "shallow" mode
Transcriptional regulatory networks allow bacteria to express proteins only when they are needed. Adaptive hypotheses explaining the evolution of regulatory networks assume that unneeded expression is costly and therefore decreases fitness, but the proximate cause of this cost is not
