Figure 4. SDSL-EPR analysis of human tektin 1 positions 81-87.

Figure 4

A) The amino acid sequence and heptad repeat pattern of human tektin 1, positions 80-99; positions 81-87 are underlined. The full heptad repeat pattern is written below the one letter amino acid code. B) Representative spectra from previously published vimentin experiments. Vimentin position 333 is a d heptad position; position 334 is an e heptad position. C) Normalized EPR spectra from human tektin 1 positions 81-87. At each position indicated, the wildtype amino acid has been replaced by cysteine and a spin label for collection of spectra. As discussed in the text, weak (w) and strong (s) components of the spectra, which are best resolved in the low field peak, are indicated.
