Abstract
In order to investigate the mechanisms of epithelial ion transports, microsomes of soybean roots were prepared and the activity of microsomal ATPases was measured by an enzyme-coupled assay. The effects of various ions were evaluated on the total activity of microsomal ATPases and the average activity was 190 nmol/min/mg protein in the control solution containing
콩 뿌리조직의 이온 흡수와 관련된 생리활성을 조사하기 위하여 뿌리조직으로부터 마이크로솜을 분리하였고, 마이크로솜 ATPase (이온점프) 활성을 분광학적 방법인 enzyme-coupled 분석방법에 따라 측정하였다. 마이크로솜 ATPase의 활성에 미치는 여러 가지 이온의 효과 또는 ATPase의 이온선택성을 조사하기 위하여
