Structure-based engineering of substrate specificity for pinoresinol-lariciresinol reductases
Pinoresinol–lariciresinol reductases (PLRs) are enzymes involved in the lignan biosynthesis. Here, crystal structures of three PLRs in the apo, substrate-bound and product-bound states, and accompanying mutagenesis provide insight into PLRs catalytic ...

Substrate Specificity of Biofilms Proximate to Historic Shipwrecks
The number of built structures on the seabed, such as shipwrecks, energy platforms, and pipelines, is increasing in coastal and offshore regions. These structures, typically composed of steel or wood, are substrates for microbial attachment and biofilm ...

The Substrate Specificity of Fumarase
Abstract 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 g fumarate g chlorofumarate g bromofumarate g acetylenedicarboxylate g iodofumarate g mesaconate ...

Do Amino Acid Antiporters Have Asymmetric Substrate Specificity?
Amino acid antiporters mediate the 1:1 exchange of groups of amino acids. Whether substrate specificity can be different for the inward and outward facing conformation has not been investigated systematically, although examples of asymmetric transport ...

Substrate specificity of human ceramide kinase
Previous studies in our laboratory have established ceramide kinase (CERK) as a critical mediator of eicosanoid synthesis. To date, CERK has not been well characterized in vitro.

Dissecting the Cytochrome P450 OleP Substrate Specificity: Evidence for a Preferential Substrate
The cytochrome P450 OleP catalyzes the epoxidation of aliphatic carbons on both the aglycone 8.8a-deoxyoleandolide (DEO) and the monoglycosylated L-olivosyl-8.8a-deoxyoleandolide (L-O-DEO) intermediates of oleandomycin biosynthesis.

Comparative Studies on Retroviral Proteases: Substrate Specificity
Exogenous retroviruses are subclassified into seven genera and include viruses that cause diseases in humans. The viral Gag and Gag-Pro-Pol polyproteins are processed by the retroviral protease in the last stage of replication and inhibitors of the HIV-1

Substrate specificity of human MCPIP1 endoribonuclease
MCPIP1, also known as Regnase-1, is a ribonuclease crucial for regulation of stability of transcripts related to inflammatory processes. Here, we report that MCPIP1 acts as an endonuclease by degrading several stem-loop RNA structures and single-stranded

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.
