This area is the part of the enzyme that controls any activity by a catalyst. The other area of the lysine, the C-terminal, is the domain that attaches itself to a substance found in the host bacteria’s cell wall. They break down the cell wall by breaking the bond peptidoglycan. The C-terminal is where the specificity comes into play, while the N-terminal is the area with the active site. Amino acids primary sequence is a chain and on this chain the N comes first and the C is on the end.
Electron microscopy is used to view bacteria and lysins. The bacteria that the lysins were applied to was looked at by this method and it showed holes in cell walls. This can be lethal to the cell. No one is sure whether or not one enzyme is capable of breaking enough of the bonds to completely kill an organism. One researcher, Loessner, believed that these phage enzymes were only used for one specific task, and many of them were needed to weaken and destroy the cell wall of an
