An enzyme that catalyzes the deamination of AMP to IMP. EC 3.5.4.6. An enzyme that catalyzes the deamination of AMP to IMP. EC 3.5.4.6. Entry Version Abbreviation Entry Term(s) 5'-AMP Deaminase Add AMP Aminase Add AMP Aminohydrolase Add AMP Deaminase Add Adenylate Deaminase Add Myoadenylate Deaminase Add Pharm Action Registry Number EC 3.5.4.6 CAS Type 1 Name The effects of adenosine deaminase on cyclic AMP accumulation were blocked by coformycin which is a potent inhibitor of the enzyme. These findings suggest that deamination of adenosine is responsible for the observed effects of adenosine deaminase preparations.

Amp deaminase

AMP deaminase (AMPD; EC 3.5.4.6) catalyzes hydrolysis of the amino group from the adenine ring of AMP resulting in production of inosine 5'-monophosphate (IMP) and ammonia. This reaction helps to maintain healthy cellular energetics by removing excess AMP that accumulates in energy depleted cells. Abstract AMP deaminase activity (AMP->IMP+NH3) is the entry reaction to the purine nucleotide cycle. In skeletal muscle, excessive energy demands during contractions leads to a net production of ADP, because ATP hydrolysis exceeds ADP rephosphorylation. Elevations in ADP increase AMP, via the myokinase reaction.

AMP deaminase(AMPD; EC 3.5.4.6) catalyzes the irreversible deamination of AMP to IMP and is one component of the purine nucleotide cycle (Fig. 187.1). AMPD is manifest in human tissues and cells as a multigene family comprising three genes.

Individuals with complete deficiency of erythrocyte AMP deaminase are healthy and have no hematologic disorders. 2014-06-26 AMP deaminase catalyses the hydrolysis of the amine group from AMP, also referred to as 5’-adenylic acid, to produce inosine 5’ monophosphate (IMP), also referred to as 5’-inosinic acid. The AMP deaminase enzyme preparation is used as a processing aid to convert AMP to IMP during the production of yeast autolysate AMP deaminase (myoadenylate deaminase; EC 3.5.4.6) is an integral part of the myofibril in skeletal muscle, and this enzyme plays an important role in energy metabolism in this tissue. The AMPD1 gene provides instructions for producing an enzyme called adenosine monophosphate (AMP) deaminase. This enzyme is found in the muscles used for movement (skeletal muscles), where it plays a role in producing energy.

Together with adenylosuccinate synthetase and adenylosuccinate lyase, it forms the purine nucleotide cycle which produces fumarate, an intermediate of the Krebs cycle, and therefore yields energy. Several AMP deaminase AMP-deaminase speelt een belangrijke rol in dit proces.

General description A cell-permeable isoquinoline derivative that acts as a specific AMP competitive inhibitor of AMP deaminase (IC 50 = 38, 27, and 24 nM for human, rat, and mice, respectively). Potentiates low frequency electrical stimulation induced increase in AMP level, AMP:ATP ratio, and phosphorylation of AMPK (at Thr172), and acetyl-CoA carboxylase (at Ser218) in contracting rat

Disease description A metabolic disorder due to lack of activity of the erythrocyte isoform of AMP deaminase. It is a clinically asymptomatic condition characterized by a 50% increase in steady-state levels of ATP in affected cells. Individuals with complete deficiency of erythrocyte AMP deaminase are healthy and have no hematologic disorders. amp + h 2 o ⇌ imp + nh 3.
