Function of your protein

This protein, In order to resist these antibodies, B-Lactamase attacks the amide bonds in the antibiotics causing deacetylation to occur.

Biological relevance and broader implications

A protein with the function of being resistant to antibodies is very important to bacteria. With this protein, the bacteria can infect the host with a disease that has a very high chance of not being stopped. A protein resistant to an antibiotic used to help cure disease is never good. By studying this protein, scientists may understand why and how it is resisting antibiotics. Once, we are able to know this information, they may use it to change the antibiotics to not be resisted by B-Lactamase so we may cure diseases. The study of this protein could also factor into other antibiotics being resisted. We can use the information we find from the study of this protein and use it towards other proteins and antibiotics so all antibiotics will not be resisted.

Important amino acids

There is one important ligand in B-Lactamase. AIX or ampicillin is bonded with key amino acids of the protein; Lys73, Ser130, and Ser70. Ser130 interacts with ampicillin by hydrogen bonding. Ser70 interacts with the oxygen on the ligand. It appears to look like it is one and the same on the ligand.

Structural highlights

This protein has eight chains. In the , each of the chains has eleven alpha helixes and nine beta-sheets. To help with the stability, some of the eight chains bind to the GOL. Within each of the chains, there are two catalytic amino acids within helix number three. In helix seven is where the last catalytic acid is. These helices and beta-sheets are very important to the structure of the protein because they represent the interactions between the polypeptides. If these interactions would be changed or removed, the whole structure would change. The function of B-Lactamase would completely change.

The tertiary structure is a . Inside this space-filling structure, you can see the ligand, ampicillin, as well as the hydrophobic(grey) and polar(amino acids).
