Photoaffinity labeling is a reliable analytical method for biological functional analysis. Three major photophores—aryl azide, benzophenone and trifluoromethyldiazirine—are utilized in analysis. Photophore-bearing l-phenylalanine derivatives, which are used for biological functional analysis, were inoculated into a Klebsiella sp. isolated from the rhizosphere of a wild dipterocarp sapling in Central Kalimantan, Indonesia, under nitrogen-limiting conditions. The proportions of metabolites were quite distinct for each photophore. These results indicated that photophores affected substrate recognition in rhizobacterial metabolic pathways, and differential photoaffinity labeling could be achieved using different photophore-containing l-phenylalanine derivatives.
光亲和标记是一种可靠的生物功能分析分析方法。分析中使用了三种主要的光基团——芳基叠氮、苯酮和三氟甲基二氮烯。用于生物功能分析的光基团修饰的l-苯丙氨酸衍生物在氮限制条件下接种到从印尼中加尔东地区野生双翅植物幼苗根际分离出的克雷伯氏菌中。各光基团的代谢物比例差异明显。这些结果表明,光基团影响根际细菌代谢通路中的底物识别,使用不同的光基团修饰的l-苯丙氨酸衍生物可以实现差异化光亲和标记。
