Substrate specificity of Ty1 integrase [PDF]
Integration of the Saccharomyces cerevisiae retrotransposon Ty1 requires the element-encoded integrase (IN) protein, which is a component of cytoplasmic virus-like particles (VLPs). Using purified recombinant Ty1 IN and an oligonucleotide integration assay based on Ty1 long terminal repeat sequences, we have compared IN activity on substrates having ...

Probing the Electrostatic and Steric Requirements for Substrate Binding in Human Platelet-Type 12-Lipoxygenase. [PDF]
Human platelet ALOX12 (hALOX12 or h12-LOX) has been implicated in a variety of human diseases. The present study investigates the active site of hALOX12 to more thoroughly understand how it positions the substrate and achieves nearly perfect regio- and ...

Substrate Specificity of Recombinant Ser/Thr Protein Kinase
Protein kinases are enzymes that phosphorylate proteins in a cell. Determination of kinase activity in reactions of phosphorylation is a very convenient way for a biochemical characterization of this group of enzymes.

Substrate specificity of the TRAMP nuclear surveillance complexes
During nuclear surveillance in yeast and human cells, the RNA exosome functions together with the TRAMP complexes. Here, the authors defined the protein composition of the TRAMP complexes and identified specific RNA binding sites for the different TRAMP ...

The generation of latent-ion-transport capacity [PDF]
Of the various hypotheses designed to explain the movement of ions from the environment into the plant cell, the most attractive suggests that ions traverse cell membranes in combination with an endogenously produced carrier substance.(1,2) The ...

Substrate specificity of prostate-specific antigen (PSA)
The serine protease prostate-specific antigen (PSA) is a useful clinical marker for prostatic malignancy. PSA is a member of the kallikrein subgroup of the (chymo)trypsin serine protease family, but differs from the prototypical member of this subgroup, tissue kallikrein, in possessing a specificity more similar to that of chymotrypsin than trypsin. We

Evolution of substrate specificity in a recipient's enzyme following horizontal gene transfer [PDF]
Despite the prominent role of horizontal gene transfer (HGT) in shaping bacterial metabolism, little is known about the impact of HGT on the evolution of enzyme function.

The Substrate Specificity of Pantethinase [PDF]
The substrate specificty of pantethinase, the mammalian enzyme which has been isolated from horse kidney cortex, has been studied. The real substrate has been found to be pantetheine in the reduced form, and the involvement of one or more—SH groups of the enzyme is also considered.A number of other compounds, chemically related to pantetheine, has also
