Common Name

Guanine

Description

Guanine, also known as G or mearlmaid aa, belongs to the class of organic compounds known as purines and purine derivatives. These are aromatic heterocyclic compounds containing a purine moiety, which is formed a pyrimidine-ring ring fused to an imidazole ring. Guanine is a moderately basic compound (based on its pKa). Guanine exists in all living species, ranging from bacteria to humans. Within humans, guanine participates in a number of enzymatic reactions. In particular, guanine and phosphoribosyl pyrophosphate can be biosynthesized from guanosine monophosphate through its interaction with the enzyme adenine phosphoribosyltransferase. In addition, guanine and ribose 1-phosphate can be biosynthesized from guanosine; which is catalyzed by the enzyme purine nucleoside phosphorylase. In humans, guanine is involved in the metabolic disorder called the gout or kelley-seegmiller syndrome pathway. Outside of the human body, Guanine is found, on average, in the highest concentration within beers and milk (cow). Guanine has also been detected, but not quantified in, several different foods, such as kombus, black radish, chinese cabbages, dills, and devilfish. This could make guanine a potential biomarker for the consumption of these foods. Guanine, with regard to humans, has been found to be associated with several diseases such as lewy body disease, frontotemporal dementia, colorectal cancer, and alzheimer's disease; guanine has also been linked to the inborn metabolic disorder lesch-nyhan syndrome. A 2-aminopurine carrying a 6-oxo substituent. Guanine is expected to be in Cannabis as all living plants are known to produce and metabolize it.

Enzyme Details

1. Adenine phosphoribosyltransferase

General function:: Involved in adenine phosphoribosyltransferase activity
Specific function:: Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
Gene Name:: APRT
Uniprot ID:: P07741
Molecular weight:: 19607.535

Enzyme Details

2. Hypoxanthine-guanine phosphoribosyltransferase

General function:: Involved in hypoxanthine phosphoribosyltransferase activity
Specific function:: Converts guanine to guanosine monophosphate, and hypoxanthine to inosine monophosphate. Transfers the 5-phosphoribosyl group from 5-phosphoribosylpyrophosphate onto the purine. Plays a central role in the generation of purine nucleotides through the purine salvage pathway.
Gene Name:: HPRT1
Uniprot ID:: P00492
