Polymorphism of S-Adenosylhomocysteine Hydrolase in Italy [PDF]
Human Heredity, 1987 S-adenosylhomocysteine hydrolase (SAHH) polymorphism has been investigated in the Italian population. Three common alleles, SAHH*1, SAHH*2 and SAHH*3, have been observed and the estimated gene frequencies are 0.968, 0.023 and 0.009, respectively. SAHH activity has been assayed in 50 healthy individuals and the mean activity was 0.043 +/- 0.017 mumol ...

Chemico-Biological Interactions, 1988
Epoxide hydrolase activity is recovered in the high-speed supernatant fraction from the liver of all mammals so far examined, including man. For some as yet unexplained reason, the rat has a very low level of this activity, so that cytosolic epoxide hydrolase is generally studied in mice.

Identification of oxidized protein hydrolase of human erythrocytes as acylpeptide hydrolase
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 2000Partial amino acid sequence of 80 kDa oxidized protein hydrolase (OPH), a serine protease present in human erythrocyte cytosol (Fujino et al., J. Biochem. 124 (1998) 1077-1085) that is adherent to oxidized erythrocyte membranes and preferentially degrades oxidatively damaged proteins (Beppu et al., Biochim. Biophys. Acta 1196 (1994) 81-87; Fujino et al.

Endo-Xylogalacturonan Hydrolase
2003Commercial pectinases used in apple juice manufacturing contain a mixture of pectin-degrading enzyme activities. Nevertheless, fragments of branched pectic molecules (or pectic hairy regions) are resistant to degradation, and can cause membrane fouling in the final ultrafiltration step of concentrated apple juice.

The Telltale Structures of Epoxide Hydrolases
Drug Metabolism Reviews, 2003Traditionally, epoxide hydrolases (EH) have been regarded as xenobiotic-metabolizing enzymes implicated in the detoxification of foreign compounds. They are known to play a key role in the control of potentially genotoxic epoxides that arise during metabolism of many lipophilic compounds.

The Nudix hydrolase superfamily
Cellular and Molecular Life Sciences CMLS, 2005Nudix hydrolases are found in all classes of organism and hydrolyse a wide range of organic pyrophosphates, including nucleoside di- and triphosphates, dinucleoside and diphosphoinositol polyphosphates, nucleotide sugars and RNA caps, with varying degrees of substrate specificity.

S-Adenosylhomocysteine Hydrolase
1986S-Adenosylhomocysteine hydrolase (AdoHcyase; EC 3.3.1.1) catalyzes the overall reaction first described by de la Haba and Cantoni (1957):

Dimetallic hydrolases and their models
Current Opinion in Chemical Biology, 2000Recent mechanistic studies of Fe3+/M2+ purple acid phosphatase present conflicting pictures about the roles of the metals. Recent model studies with Co3+/Co3+ and Fe3+/Fe3+ complexes have supported each conflicting mechanism for phosphate hydrolysis.

Publisher Summary This chapter describes structural chemistry and the biological aspects of leukotriene A4 hydrolase (LTA4). Both catalytic activities of LTA4 hydrolase are dependent on the catalytic zinc atom and are inhibited by divalent cations with different specificity and potency for each of the two activities.

Thermal resistance of pantetheine hydrolase
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1996Pantetheine hydrolase from pig kidney shows a very high resistance to denaturation with chemical denaturants, being unfolded at concentrations of guanidinium chloride higher than 6.5 M. On the contrary, chemical inactivation, followed by recording catalytic activity, occurs before conformational changes can be detected by fluorimetric or spectroscopic ...
