L-(+)-tartaric acid dihydrazide was coupled to the purple membrane from Halobacterium halobium with a water soluble carbodiimide. Gel electrophoresis analysis of the product revealed the formation of bacteriorhodopsin dimers, trimers and higher polymers. Most of the cross-links were removed by treatment with papain, demonstrating involvement of the carboxyl-rich carboxyl-terminal region of bacteriorhodopsin in the reaction. The cross-links were cleavable by periodate oxidation.
L-(+)-酒石酸二酰肼通过水溶性碳二亚胺与嗜盐菌紫膜偶联。对产物进行的凝胶电泳分析显示形成了细菌视紫红质二聚体、三聚体及更高聚物。用木瓜蛋白酶处理可去除大部分交联键，这表明细菌视紫红质富含羧基的羧基末端区域参与了该反应。这些交联键可通过高碘酸盐氧化裂解。
