L-Arginine:glycine amidinotransferase (AGAT; EC 2.1.4.1) is the enzyme that catalyses the transfer of an amidino group from L-arginine to glycine. The products are L-ornithine and glycocyamine, also known as guanidinoacetate, the immediate precursor of creatine. Creatine and its phosphorylated form play a central role in the energy metabolism ...
This may also be called standard range. In contrast, optimal (health) range or therapeutic target is a reference range or limit that is based on concentrations or levels that are associated with optimal health or minimal risk of related complications and diseases. For most substances presented, the optimal levels are the ones normally found in ...

"Providers are encouraged to consult with their local lab(s) to obtain hormone level reference ranges for both 'male' and 'female' norms, [which can vary,] and then apply the correct range when interpreting results based on the current hormonal sex, rather than the sex of registration." [3] Fenway Health: United States: 100–200 pg/mL <55 ng ...
Arginine:glycine amidinotransferase deficiency or AGAT deficiency is an autosomal recessive cerebral creatine deficiency caused by a deficiency of the enzyme arginine:glycine amidinotransferase. This enzyme deficiency results in decreased creatine synthesis, and is caused by biallelic pathogenic variants in GATM .
The standard definition of a reference range for a particular measurement is defined as the interval between which 95% of values of a reference population fall into, in such a way that 2.5% of the time a value will be less than the lower limit of this interval, and 2.5% of the time it will be larger than the upper limit of this interval, whatever the distribution of these values.
The systematic name of this enzyme class is L-arginine:1-amino-1-deoxy-scyllo-inositol-4-phosphate amidinotransferase. Other names in common use include L-arginine:inosamine-P-amidinotransferase , inosamine-P amidinotransferase , L-arginine:inosamine phosphate amidinotransferase , and inosamine-phosphate amidinotransferase .
In contrast, inhibiting arginase with ABH or other boronic acid inhibitors will maintain normal cellular levels of arginine, thus allowing for normal muscle relaxation and sexual response. [ 8 ] Arginase is a controlling factor in both male erectile function and female sexual arousal, and is therefore a potential target for treatment of sexual ...
