应用
光敏双异官能化交联剂。通常，初始反应在 7.0-8.0 的 pH 范围内偶联巯基。然后在紫外光 (250nm) 的照射下通过反应性氮烯发生二次键合。后一步的键合快速并且具有非特异性。
免责声明
还原剂（如硫醇）可将叠氮化物还原为胺类，所以应当避免还原剂出现在反应中。初始操作和偶联反应应当在弱光照条件下进行。

sigma(54)-dependent transcription requires activation by bacterial enhancer binding proteins (bEBPs). bEBPs are members of the AAA+ (ATPases associated with various cellular activities) protein family and typically form hexameric structures that are crucial for their ATPase activity. The precise mechanism by

An azidophenacyl derivative of a chemically synthesized consensus signal peptide has been prepared. The peptide, when photoactivated in the presence of rough or high-salt-stripped microsomes from pancreas, leads to inhibition of their activity in cotranslational processing of secretory pre-proteins translated
