The nucleotide sequence of the B gene of bacteriophage Mu.
Bacteriophage Mu is a highly efficient transposon which requires the products of the Mu A and B genes in order to transpose at a normal frequency. We have determined the nucleotide sequence of the B gene as well as that of the A-B intergenic region upstream of B. The protein product of the gene contains 312 amino acids and has a predicted molecular weight of 35,061. As expected, there do not ap...
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 کاملNucleotide Sequence Analysis of S1 Gene among Iranian Avian Infectious Bronchitis Viruses Isolated during 2001-2002
Infectious bronchitis (IB) virus genome codes for four structural proteins, among which the S1 subunit of spike glycoprotein comprises the major epitopes to induce neutralizing antibodies. This study involved the comparison of the full S1 sequences of five IB viruses, namely two Massachusetts and three 793/B serotypes, isolated from IB outbreaks during 2001-2002, with all other Iranian an...
متن کاملIsolation and Nucleotide Sequence of the Gene
When grown under anaerobic conditions, Neisseria gonorrhoeae, the etiologic agent of the sexually transmitted disease gonorrhea, expresses several novel outer membrane proteins. One of these, Pan 1, has an apparent molecular mass of 54 kDa in electrophoresis and is recognized by serum samples from patients with gonococcal infection. The presence of antibodies to this protein in patient sera sug...
متن کاملNucleotide sequence of a mouse tRNALeu gene
ORIGIN: The sequence was derived from i DBA-2 mouse genomic DNA fragment cloned in phage X£h4A (1) and was determined from overlapping M13 subdones as in Ref. 1. The sequence is the leftward end (as defined in Ref. 1) of a tRIAA gene cluster containing, in order, single genes encoding tRNA , tRNA A l p , tRNA G l y and tRNA l u , respectively. The (UNA, and t R N A * * coding regions are 338 bp...
