Function of your protein This protein can be found in the plant pathogenic microbe Pseudomonas syringae strain PtoDC3000. The p. syringae mutautes its host, which in this case is tomato. The p. syringae produces a toxin that cause the tomato to not be able to fight off, there for causing diseases in the tomato. The research focuses on aldehyde dehydrogenases specifically aldC. aldehyde dehydrogenases are known for its capability to detoxing aldehydes, this is important because aldehydes are very reactive, so for an example from the article they can be turned into carboxylic acids which are not as reactive, which I believe slows down the mutation. Biological relevance and broader implications Learning about the mutant and its host is relevant because it can affect the food supply, which as humans we need. Studying this mutant will give us an understanding on what the mutation is and if it can be avoided. This research can lead the farming industry to a solution to the mutant. There are many chemicals that can be found being used with crops such as weed killers and fertilizers. Important amino acids NAD+ binding site has 19 catalytic residues which consist of Ile155–Asn159, Lys182, Gly219, Ile233–Ser236, Ala239, Leu242, Glu257, Leu258, Gly259, Cys291, Glu391, and Phe393 4 catalytic amino acids known as the catalytic tetrad consisting of Asn159, Glu257, Gly288, and Cys291. Cys291 can be found to be mutated to an Ala Structural highlights Protein Structure NAD and Octanal Catalytic Tetrad Mutated Catalytic Tetrad The structure is made up of about 60% alpha helices and 30% beta sheets and 10% of other structures like water. The shape of this structure looks like its split in two bulbs with a narrow middle part, this is because it is a homodimer. It has two identical chains (A and B) covalently bonded together. You can also find two ligands in each side of the structure. This is a structure to highlight the ligand of the protein while everything else is transparent. This is to show the main structure while highlighting the interaction with the ligand. ligands The ligands that can be found in the structure are octanal and NAD+. Other important features NEED TO REWORD THIS The secondary structure features and domains of the AldC monomer are similar to those of other aldehyde dehydrogenase family members The C-terminal region consists of a mixed a/b domain, which includes the catalytic cysteine residue and forms the aldehyde-binding site" "The N-terminal Rossmann-fold domain contains a central b-sheet (b9-b8-b7- b10-b11) surrounded by a-helices to form the NAD(H)-binding site"
