    The electronic structure of S-layer proteins from Lactobacillus brevis
    (IEEE, 2008-07-28) Graham, SM; Asquith, NL; Wilde, KL; Short, KT; Holden, PJ; Stampfl, APJ; Holmes, AJ; Ruys, AJ; Stojanov, P; Riley, JD; Fang, LJ; Yang, YW; Hwu, YK
    The valence electronic structure of the S-layer of Lactobacillus brevis is determined using synchrotron-based photoelectron spectroscopy and soft X-ray absorption spectroscopy. Spectra are compared to experimental work on amino-acids and S-layers of Bacillus sphaericus. While it is indeed possible to identify energy levels with those of natural amino-acids, distinct energy shifts are indeed observed which cannot be reconciled using such simple comparisons. Furthermore a strong nitrogen signal observed in both the occupied and unoccupied energy levels suggests that the Lactobacillus brevis protein is amine-terminated. A discussion of the surface of this protein is given. © 2008 IEEE
