초록
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
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
