Xanthosine 5'-monophosphate (XMP). Acid-base and metal ion-binding properties of a chameleon-like nucleotide.
Sigel H, Operschall BP, Griesser R. Sigel H, et al. Chem Soc Rev. 2009 Aug;38(8):2465-94. doi: 10.1039/b902181g. Epub 2009 Jun 22. Chem Soc Rev. 2009. PMID: 19623361 Review.
The four acidity constants of threefold protonated xanthosine 5'-monophosphate, H(3)(XMP)(+), reveal that in the physiological pH range around 7.5 (X - H x MP)(3-) strongly dominates and not XMP(2-) as commonly given in textbooks and often applied in research papers …

Crystal structures of Trypanosoma brucei hypoxanthine - guanine - xanthine phosphoribosyltransferase in complex with IMP, GMP and XMP.
Terán D, Doleželová E, Keough DT, Hocková D, Zíková A, Guddat LW. Terán D, et al. FEBS J. 2019 Dec;286(23):4721-4736. doi: 10.1111/febs.14987. Epub 2019 Jul 24. FEBS J. 2019. PMID: 31287615 Free article.
The structures further show that a nearby water can act as an adaptor to facilitate the binding of XMP and GMP. When GMP binds, a water can accept a proton from the 2-amino group but when XMP binds, the equivalent water can donate its proton to the 2-oxo group. ...D …

Chromosomal mapping of Tmp (Emp1), Xmp (Emp2), and Ymp (Emp3), genes encoding membrane proteins related to Pmp22.
Ben-Porath I, Kozak CA, Benvenisty N. Ben-Porath I, et al. Genomics. 1998 May 1;49(3):443-7. doi: 10.1006/geno.1998.5238. Genomics. 1998. PMID: 9615230
The Tmp (tumor-associated membrane protein) gene was isolated from a c-myc induced mouse brain tumor and is expressed in several highly proliferative cell types. We have now isolated cDNAs of the mouse Xmp and Ymp genes and determined the chromosomal localization of mouse …

Acid-base and metal-ion-binding properties of xanthosine 5'-monophosphate (XMP) in aqueous solution: complex stabilities, isomeric equilibria, and extent of macrochelation.
Sigel H, Massoud SS, Song B, Griesser R, Knobloch B, Operschall BP. Sigel H, et al. Chemistry. 2006 Oct 25;12(31):8106-22. doi: 10.1002/chem.200600160. Chemistry. 2006. PMID: 16888737
The four acidity constants of threefold protonated xanthosine 5'-monophosphate, H3(XMP)+, reveal that at the physiological pH of 7.5 (XMP-H)(3-) strongly dominates (and not XMP(2-) as given in textbooks); this is in contrast to the related inosine (IMP(2-)) a …

Acid-base properties of xanthosine 5'-monophosphate (XMP) and of some related nucleobase derivatives in aqueous solution: micro acidity constant evaluations of the (N1)H versus the (N3)H deprotonation ambiguity.
Massoud SS, Corfù NA, Griesser R, Sigel H. Massoud SS, et al. Chemistry. 2004 Oct 11;10(20):5129-37. doi: 10.1002/chem.200400490. Chemistry. 2004. PMID: 15372679
The first acidity constant of fully protonated xanthosine 5'-monophosphate, that is, of H3(XMP)+, was estimated by means of a micro acidity constant scheme and the following three deprotonations of the H2(XMP)+/- (pKa=0.97), H(XMP)- (5.30), and XMP2- (6.45) s …

High level expression of XMP aminase in Escherichia coli and its application for the industrial production of 5'-guanylic acid.
Fujio T, Nishi T, Ito S, Maruyama A. Fujio T, et al. Biosci Biotechnol Biochem. 1997 May;61(5):840-5. doi: 10.1271/bbb.61.840. Biosci Biotechnol Biochem. 1997. PMID: 9178561 Free article.
To improve the efficiency of the enzymatic conversion of 5'-xanthylic acid (XMP) to 5'-guanylic acid (GMP), we attempted to increase the activity of the conversion enzyme, XMP aminase (GMP synthetase) encoded by the guaA gene in Escherichia coli. ...After 23 h of th …

Metabolic fate of AMP, IMP, GMP and XMP in the cytosol of rat brain: an experimental and theoretical analysis.
Torrecilla A, Marques AF, Buscalioni RD, Oliveira JM, Teixeira NA, Atencia EA, Günther Sillero MA, Sillero A. Torrecilla A, et al. J Neurochem. 2001 Mar;76(5):1291-307. doi: 10.1046/j.1471-4159.2001.00084.x. J Neurochem. 2001. PMID: 11238714 Free article.
A systematic study of the metabolic fate of AMP, IMP, GMP and XMP (NMP) in the presence of cytosol from rat brain is here presented; the kinetics of both disappearance of NMP, and appearance of their degradation products was followed by HPLC. ...

All this is different in the Cu(Arm)(XMP - H)- complexes, which are formed by the (XMP - H)(3-) species, that occur at the physiological pH of 7.5 and for which previously evidence has been provided that in a tautomeric equilibrium the xanthine moiety loses a proton …
