The function of starch phosphorylase has long been debated on the regulation of starch metabolism during the growth and development of plants. In this study, we isolated starch phosphorylase genes (Pho1 and Pho2) from barley, characterized their gene and protein structures, predicated their promoters cis-elements and analyzed expression patterns. Multiple alignments of these genes showed that (1) both Pho1 and Pho2 genes possess 15 exons and 14 introns in all but three of the species analyzed, Aegilops tauschii (for Pho1 which contains 16 exons and 15 introns), potato (for Pho1b which contains 14 exons and 13 introns), and Triticum uraru (for Pho2 which contains 15 exons and 14 introns); (2) the exon-intron junctions of Pho1 and Pho2 flanking the ligand-binding sites are more conservative than the other regions. Analysis of protein sequences revealed that Pho1 and Pho2 were highly homologous except for two regions, the N terminal domain and the L78 insertion region. The results of real-time ...
This entry covers several enzymes from different sources that act in vivo on different forms of (1->4)-alpha-D-glucans. -!- Some of these enzymes catalyze the first step in the degradation of large branched glycan polymers - the phosphorolytic cleavage of alpha-1,4-glucosidic bonds from the non-reducing ends of linear poly(1->4)-alpha-D-glucosyl chains within the polymers. -!- The enzyme stops when it reaches the fourth residue away from an alpha-1,6 branching point, leaving a highly branched core known as a limit dextrin. -!- The description (accepted name) of the enzyme should be modified for each specific instance by substituting glycogen with the name of the natural substrate, e.g. maltodextrin phosphorylase, starch phosphorylase, etc ...
An enzyme if a biological catalyst, it offers an alternative route with a lower Ae(Activation energy) for a certain reaction. The enzyme is composed of various structures 1° 2° tertiary or quarternary. Enzymes also contain active sites which are specific to the type of molecule that binds to them via the substrates- which are then converted into products. Sometimes enzymes contain more than one active sites- which are refered to as the alleosteric sites to which non-comp^ inhibitors can bind to ...
impact crusher,Oct 31, 2019 An impact crusher is a machine that uses striking as opposed to pressure to reduce the size of a material. Impact crushers are designated as a primary, secondary, tertiary or quarternary rotor crusher depending on which processing stage the equipment is being utilized. Common types of Impact Crushers are Horizontal Shaft Impactor (HSI) and

2. As we discussed yesterday, ferritin is an iron storage protein. Basically, it functions as a giant ball that sequesters Fe3+ by polymerizing it with oxygen-rich anions (sulfate, phosphate, hydroxide). In the PDB, look at file 1AEW. If you download it directly into RasMol, you will see just one chain, but ferritin is made up of a bunch of identical chains. So, when you have pulled up 1AEW in the PDB, look to the left-hand margin. Under other resources go to the EBI MSD Macromolecule File Server, which will give you the quarternary structure version of 1AEW. Save it on the desktop, change the filename to .pdb and open it in RasMol.. ...

Background - Our knowledge of hypertrophic cardiomyopathy (HCM) mainly originates from quarternary centres. The objective is to assess the current management of HCM patients in a large multicentre French register according to the level of expertise. Methods and results - A total of 1431 HCM patients were recruited across 26 (11 expert and 15 non-expert) centres in REMY, a prospective hospital-based register of adult HCM patients. A sarcomeric origin was suspected in 1284 (89.7%) patients [261 (20.3%) with a reported gene mutation, 242 (18.8%) genotype-negative], while 107 (7.5%) had a diagnosis of non-sarcomeric HCM. Patients managed in non-expert centres were older (P | 0.01) and presented more often with NYHA III/IV class dyspnoea (P | 0.01), congestive heart failure (P | 0.01), low LEVF (P | 0.01), less often with a syncope history (P | 0.01) and lower LV obstruction (P | 0.01) than patients in expert centres. Genotype positive sarcomeric aetiologies were less frequent in non-expert centres (P | 0

Corynebacterium glutamicum is together with C. callunae and C. efficiens a member of the diverse group of mycolic-acid containing actinomycetes, the mycolata. These bacteria are potent producer of glutamate, lysine and other amino acids on industrial scale. The cell walls of most actinomycetes contain besides an arabinogalactan-peptidoglycan complex large amounts of mycolic acids. This three-layer envelope is called MAP (mycolyl-arabinogalactan-peptidoglycan) complex and it represents a second permeability barrier beside the cytoplasmic membrane similar to the outer membrane of Gram-negative bacteria. In analogy to the situation in the outer membrane of Gram-negative bacteria, channels are present in the mycolic acid layer of the mycobacterial cell wall for the passage of hydrophilic solutes. Molecular studies have provided far-reaching findings on the amino acid flux and its balance in C. glutamicum in general, but the L-glutamate export still remains unknown. The properties of the outer ...

See also the category Nitrogen compounds. The main neutral hydride of nitrogen is ammonia (NH3), although hydrazine (N2H4) is also commonly used. Ammonia is more basic than water by 6 orders of magnitude. In solution ammonia forms the ammonium ion (NH4+). Liquid ammonia (b.p. 240 K) is amphiprotic (displaying either Brønsted-Lowry acidic or basic character) and forms ammonium and the less common amide ions (NH2-); both amides and nitride (N3-) salts are known, but decompose in water. Singly, doubly, triply and quadruply substituted alkyl compounds of ammonia are called amines (four substitutions, to form commercially and biologically important quarternary amines, results in a positively charged nitrogen, and thus a water-soluble, or at least amphiphilic, compound). Larger chains, rings and structures of nitrogen hydrides are also known, but are generally unstable. N22+ is another polyatomic cation as in hydrazine. Other classes of nitrogen anions (negatively charged ions) are the poisonous ...

Does anyone know why it is that you can get negative starch conversion in the brewhouse and then see starch later on in the process? I have seen it at 2 breweries that I have worked in where no starch is indicated and then further upstream in the process there is starch indicated. In both of these situations heating problems caused the mashes to cook way too hat too soon and that was the reason for lack of conversion. In one case an iodine stain of the wort/beer showed negative for starch

ENGLISH ABSTRACT: This project involved the analysis of genes in Solanaceae species that have previously been shown to be involved in the phosphorylation of starch or its subsequent dephosphorylation. Both these processes are essential for normal starch mobilization. A tomato conditional mutant lacking the starch phosphorylating enzyme glucan water dikinase was analyzed. It is known that starch accumulates transiently in tomato fruit and is degraded throughout the ripening process. The study aimed to determine the effect of inhibited starch degradation on fruit development. Unfortunately no effect on starch mobilisation was found in the fruit of the mutant. Immunoblot analysis revealed expression of Glucan Water Dikinase (GWD) within the fruit of the tomato mutant indicating that the conditionality of the mutation was compromised. The second set of experiments analyzed the roles of Starch Excess4 (SEX4), Like Sex Four-1 and Like Sex Four-2 (LSF1 and LSF2) in starch degradation in potato and ...

In a cationic modification process for starch, starch is reacted with polymers that contain amino and/or ammonium groups in an aqueous medium at temperatures from 115 C. to 180 C. under an increased pressure and in the absence of oxidizers, polymerization initiators and alkali. The reaction is conducted so that maximum 10% by weight starch has its molar weight reduced. Also disclosed is the use of the thus obtained reaction products as dry strength agents for paper.
