Crystallization of Chlorella deoxyuridine triphosphatase [PDF]
Acta Crystallographica Section F Structural Biology and Crystallization Communications, 2011 Deoxyuridine triphosphatase (dUTPase) is a ubiquitous enzyme that has been widely studied owing to its function and evolutionary significance. The gene coding for the dUTPase from the Chlorella alga was codon-optimized and synthesized. The synthetic gene was expressed in Escherichia coli and recombinant core Chlorella dUTPase (chdUTPase) was purified ...

The effects of calcium and magnesium ions on the adenosine triphosphatase and inosine triphosphatase activities of myosin A [PDF]
Biochemical Journal, 1969 1. The effects of Ca2+ and Mg2+ on the enzymic activity of myosin were studied with myosin preparations treated by the ion-exchange resin Chelex-100. A reaction mixture containing 0·05m-potassium chloride was chosen in which the effects of univalent ions such as K+, Na+ and Cl− do not change significantly with small variations in their concentrations ...

Molecular Characterization of Protease Activity in Serratia sp. Strain SCBI and Its Importance in Cytotoxicity and Virulence [PDF]
, 2014 A newly recognized Serratia species, termed South African Caenorhabditis briggsae isolate (SCBI), is both a mutualist of the nematode Caenorhabditis briggsae KT0001 and a pathogen of lepidopteran insects. Serratia sp.

MgATP-induced inhibition of the adenosine triphosphatase activity of the chloroform-released mitochondrial adenosine triphosphatase [PDF]
Biochemical Journal, 1981 1. Preincubation of the ox heart chloroform-released mitochondrial ATPase with MgATP results in a time-dependent inhibition of ATPase activity. No re-activation occurs when MgATP remains in the preincubation medium. The enzyme activity returns when all the MgATP in the preincubation system has been hydrolysed. 2.

RNA 5′-Triphosphatase, Nucleoside Triphosphatase, and Guanylyltransferase Activities of Baculovirus LEF-4 Protein [PDF]
Journal of Virology, 1998 ABSTRACT Autographa californica nuclear polyhedrosis virus late and very late mRNAs are transcribed by an RNA polymerase consisting of four virus-encoded polypeptides: LEF-8, LEF-9, LEF-4, and p47. The 464-amino-acid LEF-4 subunit contains the signature motifs of GTP:RNA guanylyltransferases (capping enzymes).

Inhibition of adenosine triphosphatases by gold [PDF]
Arthritis & Rheumatism, 1980 AbstractInhibition of adenosine triphosphatase (ATPase) by chlorauric acid (Au3+) and gold sodium thiomalate (Au+) was studied in dog brain and kidney and in human kidney enzyme preparations. Au3+ indiscriminately affected ouabain‐sensitive (Na+ + K+‐dependent) ATPase and ouabain‐insensitive (Mg2+‐dependent) ATPase with concentrations for 50 ...
