Abstract
Freeze-fracture of Acholeplasma laidlawii membranes from cells incubated in the presence of puromycin or omission of amino acids reveals a decrease in the number of particles between 50 and 100 angstroms in the hydrophobic fracture plane, which strongly suggests that these particles are protein. Additional evidence indicates that they may be involved in substrate transport.
摘要
对在嘌呤霉素存在下孵育的细胞或缺失氨基酸的莱氏无胆甾原体细胞膜进行冷冻断裂，结果显示在疏水断裂面上，50至100埃之间的颗粒数量减少，这有力地表明这些颗粒是蛋白质。其他证据表明，它们可能参与底物运输。
