AMP deaminase 1 is an enzyme that in humans is encoded by the AMPD1 gene. [ 5 ] [ 6 ] Adenosine monophosphate deaminase is an enzyme that converts adenosine monophosphate (AMP) to inosine monophosphate (IMP), freeing an ammonia molecule in the process.
AMP deaminase 3 is an enzyme that in humans is encoded by the AMPD3 gene. [5] [6]This gene encodes a member of the AMP deaminase gene family. The encoded protein is a highly regulated enzyme that catalyzes the hydrolytic deamination of adenosine monophosphate to inosine monophosphate, a branch point in the adenylate catabolic pathway.
Adenosine monophosphate deaminase deficiency type 1 or AMPD1, is a human metabolic disorder in which the body consistently lacks the enzyme AMP deaminase, [1] in sufficient quantities. This may result in exercise intolerance, muscle pain and muscle cramping. The disease was formerly known as myoadenylate deaminase deficiency (MADD).
AMP deaminase deficiency (formally known as myoadenylate deaminase deficiency or MADD) is a metabolic myopathy which results in excessive AMP buildup brought on by exercise. AMP deaminase is needed to convert AMP into IMP in the purine nucleotide cycle.
To change this template's initial visibility, the |state= parameter may be used: {{Nucleotide metabolism enzymes | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Nucleotide metabolism enzymes | state = expanded}} will show the template expanded, i.e. fully visible.
AMP deaminase 2 is an enzyme that in humans is encoded by the AMPD2 gene. [ 5 ] [ 6 ] High AMPD2 expression levels correlate with poor patient outcome and a proliferative tumor phenotype in undifferentiated pleomorphic sarcoma (UPS).
Adenosine monophosphate (AMP), also known as 5'-adenylic acid, is a nucleotide.AMP consists of a phosphate group, the sugar ribose, and the nucleobase adenine.It is an ester of phosphoric acid and the nucleoside adenosine. [1]
Adenosine-phosphate deaminase is found in most, if not all organisms in all tissues, however, muscle tissue is the richest source. [6] The basic pathway of adenosine-phosphate deaminase is to replace a C-N bond of a 5'-AMP to replace the carboxyl group forming 5'-IMP. 5'-IMP is then catalyzed by Inosine-5'-monophosphate dehydrogenase (IMPDH) in guanine nucleotide biosynthesis.
