Bacterial binding protein-dependent transport systems are the best characterized members of a superfamily of transporters which are structurally, functionally, and evolutionary related to each other.
Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Responsible for energy coupling to the transport system.
Enhancement of the CAMP reaction by heated milk whey and maltose when incorporated into a selective agar medium, the thallium crystal violet toxin medium (TKT), is described. Milk whey was prepared by enzyme coagulation of milk at room temperature or by acid coagulation followed by neutralization with sodium hydroxide. Concentrations of whey from 1-14% (v/v) were examined. The CAMP reaction increased with increasing whey concentration. A similar increase in the CAMP reaction was also observed with increasing concentration of maltose up to 1% (w/v), beyond which it decreased with increasing concentration of maltose. A combination of heated milk whey with maltose produced a CAMP reaction in excess of that produced by whey or maltose alone ...
Ferric carboxymaltose (Ferinject(®), Injectafer(®)) is an intravenous iron preparation approved in numerous countries for the treatment of iron deficiency. A single high dose of ferric carboxymaltose (up to 750 mg of iron in the US and 1,000 mg of iron in the EU) can be infused in a short time frame (15 min). Consequently, fewer doses of ferric carboxymaltose may be needed to replenish iron stores compared with some other intravenous iron preparations (e.g. iron sucrose). Ferric carboxymaltose improved self-reported patient global assessment, New York Heart Association functional class and exercise capacity in patients with chronic heart failure and iron deficiency in two randomized, placebo-controlled trials (FAIR-HF and CONFIRM-HF ...
In Escherichia coli L-arginine is taken up by three periplasmic binding protein-dependent transport systems that are encoded by two genetic loci: the artPIQM-artJ and argT-hisJQMP gene clusters. The transcription of the artJ, artPIQM and hisJQMP genes and operons is repressed by liganded ArgR, whereas argT, encoding the LAO (lysine, arginine, ornithine) periplasmic binding protein, is insensitive to the repressor. Here we characterize the repressible Eσ 70 P artJ, P artP and P hisJ promoters and demonstrate that the cognate operators consist of two 18 bp ARG boxes separated by 3 bp. Determination of the energy landscape of the ArgR-operator contacts by missing contact probing and mutant studies indicated that each box of a pair contributes to complex formation in vitro and to the repressibility in vivo, but to a different extent. The organization of the ARG boxes and promoter elements in the control regions of the uptake genes is distinct from that of the arginine biosynthetic genes. The hisJQMP operon

High maltose corn syrup is a food additive designed to sweeten the taste of food and increase its shelf life.The majority sugar is maltose, it contains 40-50% maltose, though some have as high as 70%. High-maltose glucose syrup is used as a substitute for normal glucose syrup in the production of hard candy. Maltose is also less humectant than glucose, so the candy produced with high-maltose syrup will not become sticky as easily as candy produced with a standard glucose syrup.. ...
ATP-binding cassette (ABC) transporters convert chemical energy from ATP hydrolysis to mechanical work for substrate translocation. They function by alternating between two states, exposing the substrate-binding site to either side of the membrane. A key question that remains to be addressed is how substrates initiate the transport cycle. Using x-ray crystallography, we have captured the maltose transporter in an intermediate step between the inward- and outward-facing states. We show that interactions with maltose-bound MBP in the periplasm induce a partial closure of the MalK dimer in the cytoplasm. ATP binding to this conformation then promotes progression to the outward-facing state. These results, interpreted in light of biochemical and functional studies, provide a structural basis to understand allosteric communication in ABC transporters.. ...

Metabolic data demonstrate that the notifiable substance [wheat glucose syrup (WGS)], as well as the read-across substances (maltose, maltitol, sorbitol, Lycasin® 80/55, and dextrin) share a common metabolic pathway as they are converted to D-glucose and/or sorbitol via hydrolysis of their glycosidic linkages by the intestinal brush border carbohydrases. On the basis of their common mono- and disaccharide metabolites, the properties of the notifiable substance, WGS is expected to be similar to the read-across substances maltose, sorbitol, maltitol, Lycasin® 80/55 and dextrin. Considering this, it is anticipated that exposure to any of the aforementioned saccharides would ultimately result in the formation of D-glucose and/or sorbitol. As such, maltose, sorbitol, maltitol, Lycasin® 80/55, and dextrin may be used as appropriate surrogates for WGS, considering their common metabolic products. According to Annex VIII, column 2, a 28-day study is not required as a suitable (sub-)chronic study is ...
I started to research the subject of malt syrup, malt extract and maltose few months back because it appears in bagel recipes and have even seen it in a pizza dough recipe. I couldnt understand what its function was. As Im now in the middle of posting about bagels part I and part II, it seems the right time to write a post on it.. This information Ive collected is mainly from How Baking Works and from Harold McGee Food & Cooking.. Making Malt Syrup. Malt syrup is germinated grain that has been fermented and can be made from any grain. It will usually have barley in it as well as other grains or if its malt extract its made only from barley and will have a much stronger malt aroma. Along with honey its an ancient world sweetener because households could use the grains they already grew for their food to make this syrup.. The process of making is in 3 stages. The first stage its germinated and then dried. The second stage its mixed with water to produce a slurry. In the third stage this ...

Carbohydrates in food are starch, cellulose (both polysaccharides), and sugars - particular sucrose, lactose (both disaccharides) and fructose. Most carbohydrates are too big to be absorbed directly and have to be broken down by enzymes. This can involve several steps.. Cellulose cannot be metabolized by human enzymes, but, as insoluble fibre, has positive effects on the colon. Cellulose gets fermented by bacteria in the large intestine.. The enzyme amylase breaks down starch into the sugar maltose (a disaccharide).. Maltose, lactose, and sucrose are split into monosaccharides, which is done by enzymes on the walls of the microvilli (called brush border hydrolases). The enzyme maltase, for instance, splits maltose into two molecules of glucose. Lactose is split into glucose and galactose. Sucrose is split into glucose and fructose. Glucose and galactose get actively transported away from the inside of the small intestines, through the cell walls of the microvilli, together with one sodium ion. ...

Pulse and pulse-chase experiments were used to study the movement of photosynthetically fixed 14C from alga to animal tissue in green hydra. The pool of mobile carbohydrate (maltose) was small, turned over rapidly and was preferentially fed with newly fixed carbon. Transport between the symbionts could also occur in darkness, and in this case the mobile maltose pool was fed from algal polysaccharide reserves. The specific activity of the maltose released by freshly isolated algae varied considerably according to experimental conditions. Cultured symbionts from European hydra do not release maltose and homogenates of animal tissue were ineffective in restoring this property. Contaminating host tissue could not be completely removed from freshly isolated symbionts during their isolation, and the possible effects that this may have on maltose release are considered. [14C]maltose received from the alga is rapidly metabolized in animal tissue. All the major animal fractions incorporate 14C, with most ...
High-maltose corn syrup is a food additive used as a sweetener and preservative. The majority sugar is maltose. It is less sweet than high-fructose corn syrup and contains little to no fructose. It is sweet enough to be useful as a sweetener in commercial food production, however. To be given the label "high", the syrup must contain at least 50% maltose. Typically, it contains 40-50% maltose, though some have as high as 70%. By using β-amylase or fungal α-amylase, glucose syrups containing over 50% maltose, or even over 70% maltose (extra-high-maltose syrup) can be produced.p. 465 This is possible because these enzymes remove two glucose units, that is, one maltose molecule at a time from the end of the starch molecule. High-maltose glucose syrup is used as a substitute for normal glucose syrup in the production of hard candy: at a given moisture level and temperature, a maltose solution has a lower viscosity than a glucose solution, but will still set to a hard product. Maltose is also less ...

Acarbose acts as an inhibitor of alpha-glucosidases and is therefore clinically used. The biosynthesis gene cluster (acb) was identified and partly characterized. The proposed model describes a pathway in which acarbose might function as a carbophor. The molecule is secreted into the medium where, after hydrolysis of starch, it is charged with additional glucose moieties. Re-uptake by a binding-protein dependent ABC importer AcbHFG would then result in a net gain of carbon and energy. Besides extracting glucose from the extracellular pool acarbose also acts as an inhibitor of alpha-amylases secreted by competitors in the natural environment. Prompted by the structural similarity between acarbose and maltotetraose, the effects of acarbose on the metabolism of maltose and maltodextrins in whole cells of E. coli and on individual components of the maltose / maltodextrin system were studied. The results demonstrate that acarbose is efficiently transported but not metabolized by E. coli due to its ...

White, odorless, sweet-tasting powder. Trehalose is a disaccharide, two simple sugars in one molecule. In trehalose (as in maltose), the two sugars are both glucose. Trehalose, like maltose, is 45% as sweet as sugar. It does not brown like sugar, and has a very low hygroscopicity (moisture attraction), so it stays free-flowing and dry. In trehalose, one glucose molecule is upside-down relative to the other. In maltose, the two glucose molecules are in the same orientation. This small difference reflects in the properties of trehalose. It does not brown when heated, it does not promote bacterial growth or tooth decay as much as maltose or sugar, and it is less attractive to moisture. Trehalose is found in honey, breads, beer, and seafood. ...
