Expression of Batis maritima methyl chloride transferase in Escherichia coli.
Methyl chloride transferase, a novel enzyme found in several fungi, marine algae, and halophytic plants, is a biological catalyst responsible for the production of atmospheric methyl chloride. A previous paper reports the purification of this methylase from Batis maritima and the isolation of a cDNA clone of the gene for this enzyme. In this paper, we describe the isolation of a genomic clone o...
متن کاملcDNA cloning of Batis maritima methyl chloride transferase and purification of the enzyme.
Methyl chloride transferase catalyzes the synthesis of methyl chloride from S-adenosine-L-methionine and chloride ion. This enzyme has been purified 2,700-fold to homogeneity from Batis maritima, a halophytic plant that grows abundantly in salt marshes. The purification of the enzyme was accomplished by a combination of ammonium sulfate fractionation, column chromatography on Sephadex G100 and ...
متن کاملDirected evolution of the alpha-L-fucosidase from Thermotoga maritima into an alpha-L-transfucosidase.
The alpha-L-fucosidase from Thermotoga maritima (Tm alpha fuc) was converted into alpha-L-transfucosidase variants by directed evolution. The wild-type enzyme catalyzes oligosaccharide synthesis by transfer of a fucosyl residue from a pNP-fucoside donor to pNP-fucoside (self-condensation) with alpha-(1-->3) regioselectivity or pNP-galactoside (transglycosylation) with alpha-(1-->2) regioselecti...
متن کاملحذف بُر آب آلوده توسط دو گیاه آبزی (Zannichellia palustris L. و Ruppia maritima L.)
زمینه و هدف: با افزایش جمعیت نیاز به منابع آب مناسب افزایش یافته است. گیاهان آبزی بومی آبهای ایران نقش به سزایی در خود پالایی منابع آب دارند. گیاهپالایی با گیاهان آبزی روشی موثر و ارزان جهت افزایش کیفیت آبها برای مصارف مختلف است. روش بررسی: در این پژوهش، طی 120 ساعت کشت گلخانهای دو گیاه آبزی زانیشلیا و شورابی در آب آبیاری آلوده‌شده با 4 سطح مختلف آلودگی بُر (0، 1، 5 و 10 میلیگرم در لیتر)، ...
متن کاملDetermination of Antioxidant Activities of Different Urginea maritima (L.) Baker Plant Extracts
The subject handled in this study is the determination of antioxidant activities of extracts obtained from the Urginea maritima (L.) Baker plant’s leaves and tubers. Extractions which were obtained using various solvents as methanol, ethanol, acetone and benzine. The antioxidant activity of the extracts was determined using β-karotene-linoleic acid system. Moreover, the free radica...
