Descriptor marcadores de fotoafinidad
Entry term(s) etiquetas de fotoafinidad
Scope note: Moléculas biológicamente activas que se unen covalentemente a las enzimas o a los ligandos proteicos que actúan normalmente sobre ellos. La unión ocurre por la activación del marcador por la luz ultravioleta. Estos enlaces se usan fundamentalmente para identificar los sitios de enlaces en las proteínas.
