Metabolite Identification
Common NameStaphyloxanthin
DescriptionStaphyloxanthin belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Based on a literature review a significant number of articles have been published on Staphyloxanthin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Staphyloxanthin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Staphyloxanthin 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.

Enzymes

General function:
Not Available
Specific function:
Catalyzes the acylation of glycosyl-4,4'-diaponeurosporenoate, i.e. the esterification of glucose at the C6'' position with the carboxyl group of the C(15) fatty acid 12-methyltetradecanoic acid, to yield staphyloxanthin. This is the last step in the biosynthesis of this orange pigment, present in most staphylococci strains (By similarity).

General function:
Not Available
Specific function:
Involved in the biosynthesis of the yellow-orange carotenoid staphyloxanthin, which plays a role in the virulence via its protective function against oxidative stress. Catalyzes the head-to-head condensation of two molecules of farnesyl diphosphate (FPP) into the colorless C(30) carotenoid 4,4'-diapophytoene (dehydrosqualene).

General function:
Not Available
Specific function:
Involved in the biosynthesis of the yellow-orange carotenoid staphyloxanthin, which plays a role in the virulence via its protective function against oxidative stress. Catalyzes three successive dehydrogenation reactions that lead to the introduction of three double bonds into 4,4'-diapophytoene (dehydrosqualene), with 4,4'-diapophytofluene and 4,4'-diapo-zeta-carotene as intermediates, and 4,4'-diaponeurosporene (the major deep-yellow pigment in staphylococci strains) as the end product.
