Multicopper oxidases can act on a broad spectrum of phenolic and non-phenolic compounds. These enzymes include laccases, which are widely distributed in plants and fungi, and were more recently identified in bacteria. Here, we present the results of biochemical and

Increasing grain yields is a major focus of crop breeders around the world. Here we report that overexpression of the rice microRNA (miRNA) OsmiR397, which is naturally highly expressed in young panicles and grains, enlarges grain size and promotes panicle

Laccases, as early as 1959, were proposed to catalyze the oxidative polymerization of monolignols. Genetic evidence in support of this hypothesis has been elusive due to functional redundancy of laccase genes. An Arabidopsis double mutant demonstrated the involvement of laccases

In this study, hydrolytic and oxidative activities of enzymes isolated from halophilic microbes were characterized and applied for biomass utilization. First, lipase from Micrococcus luteus, and peroxidase and laccase from Pseudoalteromonas phenolica and Pseudoalteromonas peptidolytica were selected and their catalytic

What is the pH optimum of Product L2157, Laccase from Rhus vernicifera?
1 Antwort-
Our own assay is performed at pH 6.5. One publication (Casella et al., J. Inorg. Biochem., 100, 2127-2139 (2006)) gives pH 6.5 as another value for the laccase from this species, with a range for enzyme activity of 4.3 to 9.

My solution of Product L2157, Laccase from Rhus vernicifera, isn't clear. Is this normal?
1 Antwort-
Yes. L2157 is a crude acetone powder, and can contain other proteins, enzymes, and cellular debris. A suspension may be prepared in 100 mM potassium phosphate buffer, pH 6.5, by homogenization with a hand-held homogenizer for 10 minutes. This preparation may then be centrifuged; the laccase activity will be present in the supernatant.
