Metabolite Identification
Common NameGuanidine
DescriptionGuanidine, also known as Gu or H2N-C(=nh)-NH2, belongs to the class of organic compounds known as guanidines. Guanidines are compounds containing a guanidine moiety, with the general structure (R1R2N)(R3R4N)C=N-R5. Guanidine is a drug which is used for the reduction of the symptoms of muscle weakness and easy fatigability associated with the myasthenic syndrome of eaton-lambert. it is not indicated for treating myasthenia gravis. Guanidine is a very strong basic compound (based on its pKa). In cattle, guanidine is involved in the metabolic pathway called the purine metabolism pathway. Guanidine is a potentially toxic compound.

Enzymes

General function:
Involved in nucleic acid binding
Specific function:
Endonuclease that catalyzes the cleavage of RNA on the 3' side of pyrimidine nucleotides. Acts on single-stranded and double-stranded RNA.
Gene Name:
RNASE1
Uniprot ID:
P61823
Molecular weight:
16461.0
General function:
Carbohydrate transport and metabolism
Specific function:
Translocates a broad array of organic cations with various structures and molecular weights including the model compounds 1-methyl-4-phenylpyridinium (MPP), tetraethylammonium (TEA), N-1-methylnicotinamide (NMN), 4-(4-(dimethylamino)styryl)-N-methylpyridinium (ASP), the endogenous compounds choline, guanidine, histamine, epinephrine, adrenaline, noradrenaline and dopamine, and the drugs quinine, and metformin. The transport of organic cations is inhibited by a broad array of compounds like tetramethylammonium (TMA), cocaine, lidocaine, NMDA receptor antagonists, atropine, prazosin, cimetidine, TEA and NMN, guanidine, cimetidine, choline, procainamide, quinine, tetrabutylammonium, and tetrapentylammonium. Translocates organic cations in an electrogenic and pH-independent manner. Translocates organic cations across the plasma membrane in both directions. Transports the polyamines spermine and spermidine. Transports pramipexole across the basolateral membrane of the proximal tubular epithelial cells. The choline transport is activated by MMTS. Regulated by various intracellular signaling pathways including inhibition by protein kinase A activation, and endogenously activation by the calmodulin complex, the calmodulin-dependent kinase II and LCK tyrosine kinase (By similarity).
