Switching substrate specificity of AMT/MEP/ Rh proteins

Substrate Recognition and Specificity of Double-Stranded RNA Binding Proteins

Recognition of double-stranded (ds) RNA is an important part of many cellular pathways, including RNA silencing, viral recognition, RNA editing, processing, and transport. dsRNA recognition is often achieved by dsRNA binding domains (dsRBDs). We use atomistic molecular dynamics simulations to examine the binding interface of the transactivation response RNA binding protein (TRBP) dsRBDs to dsRN...

Substrate Specificity of MMPs

Switching the substrate specificity of the two-component NS2B-NS3 flavivirus proteinase by structure-based mutagenesis.

The flavivirus NS2B-NS3(pro)teinase is an essential element in the proteolytic processing of the viral precursor polyprotein and therefore a potential drug target. Recently, crystal structures and substrate preferences of NS2B-NS3pro from Dengue and West Nile viruses (DV and WNV) were determined. We established that the presence of Gly-Gly at the P1'-P2' positions is optimal for cleavage by WNV...

The substrate specificity of fumarase.

The substrate specificity of fumarase has been studied by measuring the ability of the enzyme to hydrate or dehydrate derivatives of fumarate and L-malate. Fumarase was observed to hydrate fumarate and its derivatives in the order, fluorofumarate > fumarate > chlorofumarate > bromofumarate > acetylenedicarboxylate > iodofumarate > mesaconate. With the exception of fluorofumarate, water was adde...
