A molecule within a sample of a liquid is attracted equally in all directions by other molecules, so there's no net force on the molecule in any direction. Water molecules on the surface are attracted by other molecules in the liquid, but by nothing outside the liquid. This gives surface...
Serine-based β-lactamases of Class A, C and D all rely on a key water molecule to hydrolyze and inactivate β-lactam antibiotics. This process involves two conserved catalytic steps. In the first acylation step, the β-lactam antibiotic forms an acyl-enzyme intermediate (ES*) with the catal...
