Designation of TeNT Domains
The designation of TeNT domain sequences was based on previously reported sequences: TTc (Umland et al. , 1997), Light-chain (Eiselet al. , 1993), and TeNT (Eisel et al. , 1986b). TeNT comprises 1314 amino acids (the full protein without the N-terminal methionine residue (Studier, 2005)), TTc comprises amino acids 864–1314 of TeNT, LCHn comprises amino acids 1–863 of TeNT.
