Yield	Reaction Conditions	Operation in experiment
		General procedure: 4.1.1. Peptide synthesis; 4.1.2; Solid-phase peptide synthesis (SPPS) was performed with standardFmoc chemistry on rink amide resin using an automated peptidesynthesizer (Syro I, Multisyntech). The resin was loaded into a5 mL reactor with a frit at the bottom. Swelling was performed bydispensing 1 mL DMF and incubating for 15 min (2) with 10 sshaking every minute. Fmoc deprotection was achieved by treatmentwith 40percent piperidine DMF for 3 min and 20percent piperidine inDMF for 12 min (10 s/min shaking). Peptide couplings were carriedout by double couplings with Fmoc-protected amino acids(5 equiv), HBTU (5 equiv), HOBt (5 equiv) and DIPEA (10 equiv) inDMF for 40 min (10 s/min shaking). At the respective position,Fmoc-F2Pmp-OH (3 equiv) was coupled in DMF (1 mL) by manualaddition using TBTU (3 equiv), HOBt (3 equiv) and DIPEA (6 equiv)for 3 h, after 3 min preactivation. In case of the sequences for which side-chain labeling with biotinor carboxyfluorescein was planned, an additional 4-methyltrityl-(Mtt-) protected lysine was coupled to the N-terminus. Toselectively remove the Mtt group the resin was washed for 1 minwith DCM (3), deprotection was then achieved by treatment with1.8percent TFA in DCM for 3 min (10). During the deprotection the DCMsolution turned yellow.For fluorescein-labeling of the amine side-chain 5(6)-carboxyfluorescein(3 equiv), HATU (3 equiv), HOAt (3 equiv) andDIPEA (6 equiv) were dissolved in DMF and pre-activated for3 min. The solution was aspirated and coupling was allowed toproceed for 1 h. This step was repeated 4 times.For biotin-labeling of the amine side-chain the resin waswashed for 1 min in NMP (3). D-(+)-Biotin (3 equiv), HATU(3 equiv), HOAt (3 equiv) and DIPEA (6 equiv) were dissolved inNMP and pre-activated for 3 min. The solution was aspirated andcoupling was allowed to proceed for 2 h. This step was repeated2 times. N-terminal acetylation (where applicable) was achieved by dispensing800 lL of a mixture of acetic anhydride/pyridine (1:9) andreaction twice for 5 min (10 s/min shaking). After each deprotection,coupling or acetylation step, 5 washings (1 min each) withDMF were performed (10 s/min shaking).After synthesis the resin was transferred in a 5 mL syringeequipped with a frit, washed with DCM for 1 min (3) and driedin high vacuum for at least 30 min. For cleavage 1 mL of a mixtureof TFA and TIS (20:1) was added. The syringe with the mixture waskept on a shaker for 3 h. Then the liquid phase was filtered into20 mL of ice-cold Et2O. Formed precipitate was centrifuged,washed with ice-cold Et2O (2 20 mL) and purified by HPLC. 4.1.2. Azide functionalization of the N-terminus; To the peptides with the longer carbon linker, 6-azidohexanoicacid was coupled (with standard coupling conditions) to the Nterminalamine.The N-terminal amine of the peptides with the shorter linkerwas converted to an azide functionality directly on solid support.Using the compound imidazole-1-sulfonyl-azideHCl (synthesissee beneath) and modified conditions, which were reported forsolution phase chemistry from Goddard?Borger and Stick:8 Theresin was washed for 1 min each with DCM (2), DCM/MeOH(2) and MeOH (3). Then (for 40 mg resin, loading= 0.62 mmole/g) 1.4 equiv of imidazole-1-sulfonyl-azideHClin 1 mL MeOH and 100 ll of a saturated and centrifuged solutionof CuSO4*5H2O was added. After 1 min, DIPEA (1.8 equiv) wasadded and the coupling was allowed to proceed for 1 h andrepeated once more with an intermediate washing with MeOH(3 1 min).
