The lectin from leaves of Japanese cycad, Cycas revoluta Thunb. (gymnosperm) is a member of the jacalin-related family.
A novel lectin was isolated from leaves of the Japanese cycad, Cycas revoluta Thunb. (gymnosperm), and its characteristics including amino acid composition, molecular mass, carbohydrate binding specificity and partial amino acid sequences were examined. The inhibition analysis of hemagglutinating activity with various sugars showed that the lectin has a carbohydrate-binding specificity similar ...
متن کاملOccurrence and Localization of Phycoerythrin in Symbiotic Nostoc of Cycas revoluta and in the Free-Living Isolated Nostoc 7422.
The phycobiliprotein phycoerythrin was localized in symbiotic and free-living Nostoc of the cycad Cycas using immunocytochemistry. In symbiotic Nostoc, phycoerythrin was associated with the thylakoid membranes of vegetative cells and absent from heterocysts. Similar cellular/subcellular localization was observed between symbiotic Nostoc and the free-living Cycas isolate Nostoc 7422.
متن کاملEffects of buffer properties on cyclodextrin glucanotransferase reactions and cyclodextrin production from raw sago (Cycas revoluta) starch.
Results from the present study have shown that the ionic species of buffers, pH values and reaction temperature can affect the enzyme unit activities and product specificity of Toruzyme (Novo Nordisk A/S Bagsvaerd, Denmark) CGTase (cyclodextrin glucanotransferase). Applying a similar reaction environment (acetate buffer, pH 6.0; temperature, 60 degrees C), the CGTase was found to be capable of ...

در این مقاله و برای اولین بار، تعیین جنسیت سیکاس رولوتاThunb.) (Cycas revoluta، قبل از بلوغ و مخروط¬دهی، گزارش می¬شود. تعیین جنسیت سیکاس رولوتا تنها پس از بلوغ و مخروط¬دهی امکان¬پذیر است. در شرایط مطلوب، حداقل 10 تا 12 سال زمان لازم است تا سیکاس به سن بلوغ برسد. برای انجام تحقیق حاضر، تنه¬جوش¬های دوساله¬ی نر و ماده¬ی سیکاس رولوتا از پایه¬های نر و ماده¬ی بالغ جدا گردیده و در فضای آزاد، تحت شرای...
