The genomic and cDNA clones encoding cellobiohydrolase II (CBHII) have been isolated and sequenced from a native Iranian isolate of Trichoderma parceramosum, a high cellulolytic enzymes producer isolate. This represents the first report of cbhII gene from this organism. Comparison of genomic and cDNA sequences indicates this gene contains three short introns and also an open reading frame codin...

Gassericin A, a bacteriocin that was produced by Lactobacitins gasseri LA39, was treated with lysylendopeptidase and 3-bromo-3-methyl-2-(2-nitrophenyl・mercapto)3H-indole. The fragments were recovered by SDS-PAGE and sequenced. All amino acids of gassericin A were distributed by sequence analysis and the bacteriocin did not contain Qny modified amino acids. The amino acid sequence ef gassericin ...

background: the mesobuthus eupeus scorpion venoms are known to contain α-toxin peptides, many of which interfere with k+ ion channel function. these toxin peptides have important value in  the pharmacology and physiology studies of specific k+ channel of cells. objectives: given the  lack of information of the molecular biology of peptides in the toxin of iranian scorpions, the aim of this stud...

we introduce a matricial toeplitz transform and prove that the toeplitz transform of a second order recurrence sequence is another second order recurrence sequence. we investigate the injectivity of this transform and show how this distinguishes the fibonacci sequence among other recurrence sequences. we then obtain new fibonacci identities as an application of our transform.

The notion of quasi-exact sequence of modules was introduced by B. Davvaz and coauthors in 1999 as a generalization of the notion of exact sequence. In this paper we investigate further this notion. In particular, some interesting results concerning this concept and torsion functor are given.

Let  be a sequence of arbitrary random variables with  and , for every  and  be an array of real numbers. We will obtain two maximal inequalities for partial sums and weighted sums of random variables and also, we will prove complete convergence for weighted sums , under some conditions on  and sequence .

systemic lupus erythematosus (sle) is an autoimmune disease in which polymorphisms within the human leukocyte antigen (hla) region have been associated to its etiology. we conducted this study to compare the hla-dqb1 allelic sequence variation among sle patients and controls in the northeast of iran. genomic dna of 40 sle patients and 83 healthy controls were amplified by polymerase chain react...
