Metabolite Identification
Common Name4-Nitrobenzaldehyde
Description4-nitrobenzaldehyde belongs to the class of organic compounds known as nitrobenzaldehydes. These are nitrobenzenes that carry an aldehyde group at any position of the benzene ring. Based on a literature review a small amount of articles have been published on 4-nitrobenzaldehyde. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-nitrobenzaldehyde is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-Nitrobenzaldehyde is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

Enzyme Details
2. Voltage-gated potassium channel subunit beta-2
General function:
Not Available
Specific function:
Cytoplasmic potassium channel subunit that modulates the characteristics of the channel-forming alpha-subunits (PubMed:9763623, PubMed:21357749). Contributes to the regulation of nerve signaling, and prevents neuronal hyperexcitability (By similarity). Promotes expression of the pore-forming alpha subunits at the cell membrane, and thereby increases channel activity (PubMed:10896669, PubMed:16770729, PubMed:18003609, PubMed:21357749). Promotes potassium channel closure via a mechanism that does not involve physical obstruction of the channel pore (PubMed:21357749). Modulates the functional properties of KCNA4 (PubMed:9763623). Modulates the functional properties of KCNA5 (By similarity). Enhances KCNB2 channel activity (By similarity). Binds NADPH and has NADPH-dependent aldoketoreductase activity (PubMed:18672894, PubMed:21209188). Has broad substrate specificity and can catalyze the reduction of methylglyoxal, 9,10-phenanthrenequinone, prostaglandin J2, 4-nitrobenzaldehyde, 4-nitroacetophenone and 4-oxo-trans-2-nonenal (in vitro) (PubMed:18672894).
