Labeled Importin Beta Binding Domain (IBB-Alexa488/Alexa594) from importin subunit alpha-1 without denaturant

Data type: SASBDB experimental data Status: Published Curve type: Merged Last updated: 2023-06-21T07:56:39.492710+02:00

The protein contains a penultimate non-canonical amino acid p-acetylphenylalanine (207 Da) that is represented as U (selenocysteine, 168 Da) in the amino acid sequence for the entry. Therefore, the calculated MW from sequence (MW(expected)) must be adjusted accordingly (ca. 40 Da).
