Binding of Bcl-2 protein to peptides from ASPP2Ank-SH3: Fluorescence spectroscopy studies
Parent protein | Peptide no. in array | Residues | Sequence | Kd, nM |
---|---|---|---|---|
ASPP2 | 14 | 931–942 | LDSSLEGEFDLV | 142 ± 38 |
15 | 945–961 | IIYEVDDPSLPNDEGIT | 210 ± 36 | |
23 | 988–1002 | ADSDGWTPLHCAASC | 158 ± 17 | |
24 | 993–1004 | *WTPLHCAASCNN | 476 ± 40 | |
32 | 1039–1053 | GYTQCSQFLYGVQEK | No binding | |
37 | 1065–1082 | LWDYEPQNDDELPMKEGD | 96 ± 17 |
*Trp was added at the N terminus of some peptides for UV spectroscopy.
†ASPP2 978–988 was not tested because we were unable to label it with fluorescein.
