Plant peroxidases: substrate complexes with mechanistic implications.
Plant peroxidases are capable of binding phenolic substrates, and it has been possible to crystallize complexes between horseradish peroxidase C (HRP C) and benzhydroxamic acid. The X-ray structures of the binary HRP C:ferulic acid complex and the ternary HRP C:CN(-):ferulic acid complex to 2.0 and 1.45 A resolution, respectively, have also been solved recently. Ferulic acid is a naturally occu...
متن کاملInteractions between small heat shock protein subunits and substrate in small heat shock protein-substrate complexes.
Small heat shock proteins (sHSPs) are dynamic oligomeric proteins that bind unfolding proteins and protect them from irreversible aggregation. This binding results in the formation of sHSP-substrate complexes from which substrate can later be refolded. Interactions between sHSP and substrate in sHSP-substrate complexes and the mechanism by which substrate is transferred to ATP-dependent chapero...
متن کاملGene delivery through cell culture substrate adsorbed DNA complexes.
Efficient gene delivery is a fundamental goal of biotechnology and has numerous applications in both basic and applied science. Substrate-mediated delivery and reverse transfection enhance gene transfer by increasing the concentration of DNA in the cellular microenvironment through immobilizing a plasmid to a cell culture substrate prior to cell seeding. In this report, we examine gene delivery...
متن کاملFibrinogen substrate recognition by staphylocoagulase.(pro)thrombin complexes.
Thrombin generation and fibrinogen (Fbg) clotting are the ultimate proteolytic reactions in the blood coagulation pathway. Staphylocoagulase (SC), a protein secreted by the human pathogen Staphylococcus aureus, activates prothrombin (ProT) without proteolysis. The SC.(pro)thrombin complex recognizes Fbg as a specific substrate, converting it directly into fibrin. The crystal structure of a full...
متن کاملSubstrate channeling and enzyme complexes for biotechnological applications.
Substrate channeling is a process of transferring the product of one enzyme to an adjacent cascade enzyme or cell without complete mixing with the bulk phase. Such phenomena can occur in vivo, in vitro, or ex vivo. Enzyme-enzyme or enzyme-cell complexes may be static or transient. In addition to enhanced reaction rates through substrate channeling in complexes, numerous potential benefits of su...
