Metabolite Identification
Common NamePhenylephrine
DescriptionPhenylephrine, also known as mesaton or fenilefrina, belongs to the class of organic compounds known as 1-hydroxy-4-unsubstituted benzenoids. These are phenols that are unsubstituted at the 4-position. Phenylephrine is a very strong basic compound (based on its pKa). Phenylephrine is a bitter tasting compound. Outside of the human body,. It is often used in combination with tropicamide as a synergist when tropicamide alone is not sufficient.

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the oxidative deamination of biogenic and xenobiotic amines and has important functions in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues. MAOA preferentially oxidizes biogenic amines such as 5-hydroxytryptamine (5-HT), norepinephrine and epinephrine.
Gene Name:
MAOA
Uniprot ID:
P21397
Molecular weight:
59681.27
General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
Alpha-2 adrenergic receptors mediate the catecholamine- induced inhibition of adenylate cyclase through the action of G proteins. The rank order of potency for agonists of this receptor is oxymetazoline > clonidine > epinephrine > norepinephrine > phenylephrine > dopamine > p-synephrine > p-tyramine > serotonin = p-octopamine. For antagonists, the rank order is yohimbine > phentolamine = mianserine > chlorpromazine = spiperone = prazosin > propanolol > alprenolol = pindolol

Uniprot ID:
P18089
Molecular weight:
49953.1
General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
This alpha-adrenergic receptor mediates its action by association with G proteins that activate a phosphatidylinositol- calcium second messenger system. Its effect is mediated by G(q) and G(11) proteins

Uniprot ID:
P35368
Molecular weight:
56835.4
General function:
Involved in nucleotide binding
Specific function:
May be a regulated effector of stress granule assembly. Phosphorylation-dependent sequence-specific endoribonuclease in vitro. Cleaves exclusively between cytosine and adenine and cleaves MYC mRNA preferentially at the 3'-UTR. ATP- and magnesium-dependent helicase. Unwinds preferentially partial DNA and RNA duplexes having a 17 bp annealed portion and either a hanging 3' tail or hanging tails at both 5'- and 3'-ends. Unwinds DNA/DNA, RNA/DNA, and RNA/RNA substrates with comparable efficiency. Acts unidirectionally by moving in the 5' to 3' direction along the bound single-stranded DNA.
