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 ...

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.

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 ...

Oscillation-like diffusion of two-dimensional liquid dusty plasmas on one-dimensional periodic substrates with varied widths [PDF]
The long-time diffusion of two-dimensional dusty plasmas on a one-dimensional periodic substrate with varied widths is investigated using Langevin dynamical simulations. When the substrate is narrow and the dust particles form a single row, the diffusion is the smallest in both directions.

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

Jumonji C (JmjC) lysine demethylases (KDMs) catalyze the removal of methyl (-CH3) groups from modified lysyl residues. Several JmjC KDMs promote cancerous properties and these findings have primarily been in relation to histone demethylation.

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

Elucidation of substrate specificity in Aspergillus nidulans UDP-galactose-4-epimerase. [PDF]
The frequency of invasive fungal infections has rapidly increased in recent years. Current clinical treatments are experiencing decreased potency due to severe host toxicity and the emergence of fungal drug resistance.

Substrate Specificity of Chlorophyllase [PDF]
Apparent Km and V(max) values were obtained for hydrolysis of methyl and ethyl chlorophyllides a, methyl and ethyl pheophorbide a, and 9-hydroxymethyl pheophorbide a by chlorophyllase from Ailanthus altissima. Analysis of substrate specificity data for chlorophyllase indicates that the presence of a 9-keto group and a methyl alcohol group esterified at
