آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولNucleotide sequence of the cellobiohydrolase gene from Trichoderma viride.
The filamentous fungus, Trichoderma viride, secretes large amounts of several cellulolytic enzymes (1). We report here the nucleotide sequence of the gene coding for exo-cellobiohydrolase (CBH), which accounts for more than 65% of the total cellulase content. This gene was isolated from a T. viride genomic library using a 30mer oligonucleotide based on the sequence of the reported CBHI gene of ...
متن کاملEnzymes That Hydrolyze Fungal Cell Wall Polysaccharides I. PURIFICATION AND PROPERTIES OF AN ENDO-m-(1 + 3)-GLUCANASE FROM TRICHODERMA VIRIDE*
An endo-a-D-(1 + 3).glucanase capable of hydrolyzing various ~(1 -+ 3).glucans has been isolated and purified from the culture filtrate of the cellulolytic fungus Trichoderma viride, and its specificity has been examined. Of the compounds tested only those with oc-(1 ---f 3).glucosidic linkages were attacked, and the enzymatic hydrolysis occurred with retention of configuration of the anomeric ...
متن کاملSuppression of Pratylenchus penetrans and Tylenchorhynchus dubius by Trichoderma viride.
Trichoderma spp. are common soil fungi which influence tile development of plant-pathogenic fungi in the soil (1, 8). Yang et al. (9) found that T. harzianum influenced the severity of Fusarium wilt of cotton in the presence of Meloidogyne incognita. We report herein that the survival of two other plant-parasitic nematodes also was influenced by addit ion of cornminuted cultures of Trichoderrna...
متن کاملEnhanced cellulase production by a mutant of Trichoderma viride.
A mutant strain that secretes twice as much cellulase as its parent was obtained by irradiating conidia of Trichoderma viride QM 6a with a linear accelerator.
