Adenine phosphoribosyltransferase isoforms of Arabidopsis and their potential contributions to adenine and cytokinin metabolism.

Physiologia plantarum

Allen M, Qin W, Moreau F, Moffatt B.
PMID: 12010467
Physiol Plant. 2002 May;115(1):56-68. doi: 10.1034/j.1399-3054.2002.1150106.x.

Adenine phosphoribosyltransferase (APT; EC 2.4.2.7) is a constitutively expressed enzyme involved in the one-step salvage of adenine to AMP. The Arabidopsis thaliana genome contains five sequences annotated as encoding APT or APT-like enzymes. Three of these have now been...

Biochem J. 1966 Sep;100(3):664-70. doi: 10.1042/bj1000664.

1. The activities of adenine phosphoribosyltransferase and hypoxanthine phosphoribosyltransferase in extracts of rat and mouse liver, brain, spleen, heart and kidney, of rat bone marrow and of Ehrlich ascites-tumour cells have been measured. The specific activity of adenine phosphoribosyltransferase...

Changes of purine and pyrimidine nucleotide biosynthesis during shoot initiation from epicotyl explants of white spruce (Picea glauca).

Plant science : an international journal of experimental plant biology

Stasolla C, Loukanina N, Ashihara H, Yeung EC, Thorpe TA.
PMID: 22980203
Plant Sci. 2006 Sep;171(3):345-54. doi: 10.1016/j.plantsci.2006.04.004. Epub 2006 May 15.

Nucleotide metabolism was investigated during white spruce organogenesis by following the metabolic fate of (14)C-labeled adenine, adenosine and inosine, as purine precursors, and orotic acid, uridine, and uracil, as pyrimidine intermediates. Key enzymes of purine and pyrimidine metabolism were...

Dihydroxyadenine crystal-induced nephropathy presenting with rapidly progressive renal failure.

Kidney research and clinical practice

Verma R, Niraimathi M, Prasad P, Agrawal V.

Kidney Res Clin Pract. 2018 Sep;37(3):287-291. doi: 10.23876/j.krcp.2018.37.3.287. Epub 2018 Sep 30.

Adenine phosphoribosyltransferase enzyme deficiency is a rare, autosomal recessive disorder. It is a disease limited to the renal system and usually presents with urolithiasis. Herein, we report a young female with dihydroxyadenine (DHA) crystal-induced nephropathy presenting with rapidly progressive...

Phosphorylation of cytokinin by adenosine kinase from wheat germ.

Plant physiology

Chen CM, Eckert RL.
PMID: 16659870
Plant Physiol. 1977 Mar;59(3):443-7. doi: 10.1104/pp.59.3.443.

Adenosine kinase was partially purified from wheat germ. This enzyme preparation, which was devoid of adenine phosphoribosyltransferase and nearly free of adenosine deaminase but contained adenylate kinase, rapidly phosphorylated adenosine and a cytokinin, N(6)-(delta(2)-isopentenyl)adenosine. Electrophoretic analysis indicated that only...

Adenine phosphoribosyltransferase (APRT) deficiency: a new genetic mutation with early recurrent renal stone disease in kidney transplantation.

NDT Plus. 2010 Oct;3(5):436-8. doi: 10.1093/ndtplus/sfq096. Epub 2010 Jun 02.

Adenine phosphoribosyltransferase (APRT) deficiency, a rare inborn error inherited as an autosomic recessive trait, presents with 2,8-dihydroxyadenine (2,8-DHA) crystal nephropathy. We describe clinical, biochemical and molecular findings in a renal transplant recipient with renal failure, 2,8-DHA stones and no...

Lack of cross-resistance to FF-10501, an inhibitor of inosine-5'-monophosphate dehydrogenase, in azacitidine-resistant cell lines selected from SKM-1 and MOLM-13 leukemia cell lines.

Pharmacology research & perspectives

Murase M, Iwamura H, Komatsu K, Saito M, Maekawa T, Nakamura T, Yokokawa T, Shimada Y.
PMID: 26977297
Pharmacol Res Perspect. 2016 Jan 28;4(1):e00206. doi: 10.1002/prp2.206. eCollection 2016 Feb.

Resistance to azacitidine is a major issue in the treatments of myelodysplastic syndrome and acute myeloid leukemia, and previous studies suggest that changes in drug metabolism are involved in the resistance. Therefore, drugs with mechanisms resistant or alternative to...

Adenine phosphoribosyltransferase (APRT) deficiency is a rare disorder caused by an autosomal recessive genetic disease leading to the deposition of 2,8-dihydroxyadenine (2,8-DHA) in the kidney. The disease remains under-recognized, oftentimes diagnosed in late stages of renal insufficiency or a...
