Function of your protein

serve as a metabolic housekeeping enzyme due to their ability to detoxify aldehydes, which are highly reactive compounds generated through cellular. They can also scavenge aldehyde from lipid peroxidation and convert them to a less chemically reactive carboxylic acid. Aldc additionally play an important role in ethanol metabolism via oxidation of acetaldehyde into acetate, metabolism of polyamine, and plant cell wall ester biogenesis. The bacterial pathogen Pseudomonas syringae is the organism that is causing mutation in the host. It turns out that 8 carbon carbon substrate is the preferred aliphatic aldehyde substrate in this case Octanal, which is surrounded by aromatic rings. Octanal has the lowest Km and highest Vmax values and NAD+ is the cofactor.

Biological relevance and broader implications

The bacterial pathogen peudomanas syringae is used as a model for understanding microbial evolution, how host and pathogens interact and bacterial virulence mechanisms. P.syringae utilizes several strategies to manipulate hormone signaling in its host plants. These interactions help agriculturalists to detect diseases in plants and how to protect crops from being invaded by these harmful pathogens. In order to suppress host defenses and promote disease development, P. syringae produces a wide variety of virulence factors including auxin Indole-3-acetic acid (IAA) synthesis, whose production is implicated in pathogen virulence. PtoDC3000 synthesizes IAA using an uncharacterized pathway that requires indole-3-acetaldehyde dehydrogenase.

Important amino acids

In order to determine the substrate preference of AldC, a panel of 23 molecules including short to long chain aliphatic aldehydes was used to screen for enzymatic activity. Spectrophotometric assays of AldC identified aliphatic aldehydes of 5-9 carbon length as substrates. It turns out that the 8 carbon carbon substrate is the preferred aliphatic aldehyde substrate in this case Octanal, which is surrounded by aromatic rings. On the comparison table, data suggest that short 2-4 carbon aldehydes, branched aliphatic aldehydes and larger aromatic aldehydes are poor substrates. Octanal has the lowest Km and highest Vmax values. as you can be by the really amazing ligand that is bound to it.

Structural highlights

has two domains, hydrophobic and hydrophilic regions. The N-terminus of Aldc contains a central beta sheet surrounded by alpha helices which forms the NAD(H)-binding site. Additionally, around the C-terminus there is a mixture of alpha and beta domains which the cysteine residue and forms the aldehyde binding site. A small three stranded beta sheet domain facilitates aligomerization. There is an interdomain linker region that connects the N and C terminal domains of Aldc.
