Substrate specificity of rat brain ceramidase

Journal of Lipid Research, 2002
In this study, the substrate specificity of a newly identified rat brain ceramidase (CDase) was investigated. To this end, the major functional groups and stereochemistry of ceramide (Cer) were evaluated for their influence on the hydrolysis of substrate

Substrate Specificity of Biofilms Proximate to Historic Shipwrecks

Microorganisms, 2023
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 ...

Structure-based engineering of substrate specificity for pinoresinol-lariciresinol reductases

Nature Communications, 2021
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 ...

Do Amino Acid Antiporters Have Asymmetric Substrate Specificity?

Biomolecules, 2023
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 and the effect of calcium on Trypanosomabrucei metacaspase 2 [PDF]

, 2013
Metacaspases are cysteine peptidases found only in yeast, plants and lower eukaryotes, including the protozoa. To investigate the extended substrate specificity and effects of Ca²⁺ on the activation of these enzymes, detailed ...

Substrate specificity of human ceramide kinase

Journal of Lipid Research, 2005
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

Biomolecules, 2020
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

Viruses, 2010
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

Bacillus anthracis edema factor substrate specificity: evidence for new modes of action [PDF]

, 2012
Since the isolation of Bacillus anthracis exotoxins in the 1960s, the detrimental activity of edema factor (EF) was considered as adenylyl cyclase activity only.
