"[..] polyserine tract of AmVg and NvVg were synthesized by CPC Scientific (Sunnyvale, CA, USA) for NMR analysis. The synthesis was performed after isotope-labeling expression attempts in Escherichia coli were deemed unsuitable [..] The peptides had the following sequences: AmVg (residues 358–392): EKLKQDILNLRTDISTS(Sp)SS(15I)SSSEENDFWQPKPT AmVg (residues 336–385): R(15V)SKT(15A)MNSNQI(15V)SDNS(15L)-(15S)STEEK(15L)KQDI(15L)N(15L)RTDI(15S)S(15S)(Sp)S(15A)IS (15S)(15S)EEND. NvVg (residues 351–385): EHKHSDESTSE(Sp)FES(15I)ADNNDDSYFQRKPKLTEAP." NvVg (residues 335–372): RPNK(15L)N(15L)QRRHDHKS(15G)EHKHSDE(15S)S-(15S)E(Sp)FE(15A)I(15A)DNNDD.
