Site-directed mutagenesis of the leech-derived factor Xa inhibitor antistasin. Probing of the reactive site

Probing the phosphocholine-binding site of human C-reactive protein by site-directed mutagenesis.

Human C-reactive protein (CRP) can activate the classical pathway of complement and function as an opsonin only when it is complexed to an appropriate ligand. Most known CRP ligands bind to the phosphocholine (PCh)-binding site of the protein. In the present study, we used oligonucleotide-directed site-specific mutagenesis to investigate structural determinants of the PCh-binding site of CRP. E...

Probing the substrate binding site of Candida tenuis xylose reductase (AKR2B5) with site-directed mutagenesis.

Little is known about how substrates bind to CtXR (Candida tenuis xylose reductase; AKR2B5) and other members of the AKR (aldo-keto reductase) protein superfamily. Modelling of xylose into the active site of CtXR suggested that Trp23, Asp50 and Asn309 are the main components of pentose-specific substrate-binding recognition. Kinetic consequences of site-directed substitutions of these residues ...

Site-Directed Mutagenesis in Human Granulocyte-colony Stimulating Factor, Cloning and Expression in Escherichia coli

Human granulocyte colony stimulating factor (hG-CSF) induces proliferation and differentiation of granulocyte progenitor cells. This glycoprotein is currently being used for treatment of neutropenia, in patients who have undergone bone marrow transplantation. So far, different researchers have tried to enhance hG-CSF biological activity and stability. In this study, Polymerase Chain Reaction (P...
