study of cohesive devices in the textbook of english for the students of apsychology by rastegarpour
this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
Crystal structure of nucleotide-free diphtheria toxin.
The crystal structure of diphtheria toxin (DT) in the absence of nucleotide (nucleotide-free DT) has been determined at 2.3 A resolution to a crystallographic R factor and free R factor of 18.2 and 28.2%, respectively. A comparison of this structure to the previously determined structures of DT in complex with adenyly(3'-5')uridine monophosphate (ApUp) and DT in complex with nicotinamide adenin...
متن کاملNucleotide sequence of Clostridium difficile toxin B gene
Clostridium difficile, the causative agent of antibiotic-associated pseudomembranous colitis, produces two toxins, A and B (1). Toxin A is both an enterotoxin and cytotoxin, whereas toxin B is a highly potent cytotoxin (2,3,4). Toxin A has been cloned and sequenced by our research team (5) and later by Sauerborn and von Eichel-Streiber (6). The entire coding region of toxin B and 398 bp of the ...
متن کاملThe complete nucleotide sequence of tetanus toxin.
We have previously isolated and sequenced a portion of the structural gene for tetanus toxin from C.tetani CN3911 (1). Overlapping clones encoding the entire gene have now been isolated and the full sequence is reported below. Our designation of the start of translation is based on amino terminal analysis (2) and partial ami no acid sequence of the toxin (3). The methionine residue before the p...
متن کاملCloning of the structural gene for Clostridium botulinum type C1 toxin and whole nucleotide sequence of its light chain component.
The toxigenicity of Clostridium botulinum type C1 is mediated by specific bacteriophages. DNA was extracted from one of these phages. Two DNA fragments, 3 and 7.8 kb, which produced the protein reacting with antitoxin serum were cloned by using bacteriophage lambda gt11 and Escherichia coli. Both DNA fragments were then subcloned into pUC118 plasmids and transferred into E. coli cells. The nucl...
