Replacement schedules with hydrocortisone (HC) to treat 21OHD are generally unsatisfactory and partially successful regarding growth. Noncompliance is common since its short half-life requires TID administration. Even multiple daily HC doses do not reproduce cortisol chronobiology and may disturb hypothalamic-mediated rhythms. Because synthetic glucocorticoids could improve clinical control, we evaluated the possible benefits of a one-year treatment period with a single morning oral dose of prednisolone ( ...

Anaerobic cellulolytic bacteria organize a comprehensive range of cellulases and hemicellulases in high molecular weight multienzyme complexes termed cellulosomes. Integration of cellulosomal components occurs via highly ordered protein-protein interactions between cohesins and dockerins. This paper reports the production of mini-cellulosomes containing one (GH16-1C) or three (GH16-3C) copies of Clostridium thermocellum glucanase 16A (CtGlc16A). Barley β-1,3-1,4-glucans are known to be antinutritive ...

Barley-based diets contain a significant proportion of highly soluble 1,3-1,4-β-glucans that display anti-nutritive properties for monogastric animals, in particular for poultry. Cleavage of mixed linked glucans by the addition of exogenous enzymes leads to a significant reduction in the degree of polymerization of the polysaccharide and a consequent reduction of digesta viscosity. Plant cell wall 1,3-1,4-β-glucans may be hydrolyzed by 1,3-1,4-β-glucanases (EC 3.2.1.73) or by 1,4-β-glucanases (EC ...

Cellulosomes, synthesized by anaerobic microorganisms such as Clostridium thermocellum, are remarkably complex nanomachines that efficiently degrade plant cell wall polysaccharides. Cellulosome assembly results from the interaction of type I dockerin domains, present on the catalytic subunits, and the cohesin domains of a large non-catalytic integrating protein that acts as a molecular scaffold. In general, type I dockerins contain two distinct cohesin-binding interfaces that appear to display identical ...

21-Hydroxylase deficiency (21-OHD) is the most common form of congenital adrenal hyperplasia (CAH), followed by 11β-hydroxylase deficiency (11β-OHD). Diagnostic serum markers for these conditions are 17-hydroxyprogesterone (17-OHP) and 11- desoxycortisol (S), respectively. In 21-OHD, the large amounts of 17-OHP are further 11β-hydroxylated to form 21-deoxycortisol (21-DF), making it also an excellent marker of this disease. These steroids can be measured in blood by radioimmunoassay (RIA). In this paper, ...

ABSTRACT In general, cellulases and hemicellulases are modular enzymes in which the catalytic domain is appended to one or more noncatalytic carbohydrate binding modules (CBMs). CBMs, by concentrating the parental enzyme at their target polysaccharide, increase the capacity of the catalytic module to bind the substrate, leading to a potentiation in catalysis. Clostridium thermocellum hypothetical protein Cthe_0821, defined here as C. thermocellum Man5A, is a modular protein comprising an N-terminal ...

The cloning, expression and characterization of three cellulosomal pectinolytic enzymes viz., two variants of PL1 (PL1A and PL1B) and PL9 from Clostridium thermocellum was carried out. The comparison of the primary sequences of PL1A, PL1B and PL9 revealed that these proteins displayed considerable sequence similarities with family 1 and 9 polysaccharide lyases, respectively. PL1A, PL1B and PL9 are the putative catalytic domains of protein sequence ABN54148.1 and ABN53381.1 respectively. These two ...

Animal venoms are large, complex libraries of bioactive, disulphide-rich peptides. These peptides, and their novel biological activities, are of increasing pharmacological and therapeutic importance. However, recombinant expression of venom peptides in Escherichia coli remains difficult due to the significant number of cysteine residues requiring effective post-translational processing. There is also an urgent need to develop high-throughput recombinant protocols applicable to the production of ...

Many animal species exhibit laterality in sensation and behavioral responses, namely, the preference for using either the left or right side of the sensory system. For example, some fish use their left eye when observing social stimuli, whereas they use their right eye to observe novel objects. However, it is largely unknown whether such laterality in sensory-behavior coupling evolves during rapid adaptation processes. Here, in the Mexican tetra, Astyanax mexicanus, we investigate the laterality ...

Congenital adrenal hyperplasia caused by classic 21-hydroxylase deficiency (21OHD) is an autosomal recessive disorder with a high prevalence of asymptomatic heterozygote carriers (HTZ) in the general population, making case detection desirable by routine methodology. HTZ for classic and nonclassic (NC) forms have basal and ACTH-stimulated values of 17-hydroxyprogesterone (17OHP) that fail to discriminate them from the general population. 21-Deoxycortisol (21DF), an 11-hydroxylated derivative of 17OHP, ...

21-Hydroxylase deficiency (21OHD) is the most common cause of congenital adrenal hyperplasia, followed in frequency by 11beta-hydroxylase deficiency (11betaOHD). Although the relative frequency of 11betaOHD is reported as between 3 and 5% of the cases, these numbers may have been somewhat underestimated.In 133 patients (89 females/44 males; 10 d-20.9 yr) with alleged classic 21OHD and five (three females/two males; 7.3-21 yr) with documented 11betaOHD, we measured serum 21-deoxycortisol (21DF), 17-hydroxyprogesterone ( ...

Noncatalytic carbohydrate-binding modules (CBMs), which are found in a variety of carbohydrate-degrading enzymes, have been grouped into sequence-based families. CBMs, by recruiting their appended enzymes onto the surface of the target substrate, potentiate catalysis particularly against insoluble substrates. Family 6 CBMs (CBM6s) display unusual properties in that they present two potential ligand-binding sites termed clefts A and B, respectively. Cleft B is located on the concave surface of the ...
