ВЛИЯНИЕ СВЕТА НА АКТИВНОСТЬ СУКЦИНАТДЕГИДРОГЕНАЗЫ<br /> В ЛИСТЬЯХ КУКУРУЗЫ
Journal Title: Журнал ÑтреÑÑ-физиологии и биохимии - Year 2005, Vol 1, Issue 1
Abstract
Фотосинтез и дыхание дают энергию растениям в разных световых условиях. В связи с этим, очень важно обеспечить тонкую регуляцию этих процессов. В данной работе нами показано падение активности сукцинатдегидрогеназы в интактных листьях на свету. Прямого действия света на очищенный фермент не обнаружено. Показано, что малые концентрации АТФ (2 - 5 мкМ) активировали сукцинатдегидрогеназу (СДГ), высокие концентрации (более 30 мкМ) - ингибировали. Полученные данные позволяют предположить, что регуляция фермента осуществляется через интермедиаты клеточного метаболизма.
