Broder Rühmann et al.
Journal of chromatography. A, 1350, 44-50 (2014-05-28)
A fast carbohydrate screening platform processible in 96-well format is described. The method is suitable for the determination of various carbohydrates out of complex mixtures as obtained by acidic hydrolysis of carbohydrates polymers. The chromatographic conditions for an efficient separation
Buetusiwa Thomas Menavuvu et al.
Journal of bioscience and bioengineering, 102(5), 436-441 (2006-12-26)
d-Arabinose isomerase from Klebsiella pneumoniae 40bXX was purified 12-fold with a 62.5% yield indicated by its electrophoretic homogeneity. The purified enzyme showed the highest activities toward d-arabinose and l-fucose as substrates at optimum conditions (50 mM glycine-NaOH, pH 9.0, 40
Yasuro Shinohara et al.
Carbohydrate research, 493, 108019-108019 (2020-05-16)
The susceptibility to glycation of all d-glucose-containing reducing disaccharides (kojibiose, sophorose, nigerose, laminaribiose, maltose, cellobiose, isomaltose, and gentiobiose) was evaluated by Maillard browning and the percentages of their acyclic forms estimated using a novel method to evaluate reactivity toward oxime
Jinjin Diao et al.
Biochemical and biophysical research communications, 499(4), 941-947 (2018-04-08)
Oxygen supply is an important factor during Crypthecodinium cohnii fermentation for docosahexaenoic acid (DHA) production. However, few studies about the intrinsic correlation between dissolved oxygen (DO) and cellular metabolism have been reported. In this study, the responses of C. cohnii to
Louis Patrick Conway et al.
Carbohydrate research, 455, 39-44 (2017-11-24)
Galactokinases are a class of enzymes which belong to the GHMP (galactokinase, homoserine kinase, mevalonate kinase, and phosphomevalonate kinase) superfamily and catalyse the phosphorylation of galactose in the first step of the Leloir pathway. Here we report the discovery of
Yo-Han Ju et al.
Biotechnology letters, 32(2), 299-304 (2009-10-27)
A recombinant L-fucose isomerase from Caldicellulosiruptor saccharolyticus was purified as a single 68 kDa band with an activity of 76 U mg(-1). The molecular mass of the native enzyme was 204 kDa as a trimer. The maximum activity for L-fucose
Yu Gao et al.
Bioscience, biotechnology, and biochemistry, 83(11), 2097-2109 (2019-07-03)
Maltose phosphorylase (MP), a glycoside hydrolase family 65 enzyme, reversibly phosphorolyzes maltose. In this study, we characterized Bacillus sp. AHU2001 MP (MalE) that was produced in Escherichia coli. The enzyme exhibited phosphorolytic activity to maltose, but not to other α-linked
Carine Vergne-Vaxelaire et al.
Applied microbiology and biotechnology, 102(13), 5569-5583 (2018-05-08)
Most of the "repressor, open reading frame, kinase" (ROK) proteins already characterized so far, and exhibiting a kinase activity, take restrictedly D-glucose as substrate. By exploring the sequenced bacterial diversity, 61 ATP-dependent kinases belonging to the ROK family have been
Wataru Saburi et al.
Biochimie, 144, 63-73 (2017-11-07)
d-Mannose isomerase (MI) reversibly isomerizes d-mannose to d-fructose, and is attractive for producing d-mannose from inexpensive d-fructose. It belongs to the N-acylglucosamine 2-epimerase (AGE) superfamily along with AGE, cellobiose 2-epimerase (CE), and aldose-ketose isomerase (AKI). In this study, Marinomonas mediterranea
