Serine revised

Schalley and Weis [98] revised the results obtained by several studies on hydrogen bonded serine dimers. Those have reported the formation of unusually stable protonated serine octamers, with a clear preference for homochirality [99-103]. Mixed l- and D-serine clusters show up in a small ratio vs. the homochiral ones. 

Figure 6. Structures of ferrichrome and alhomycin. The nature of the spacer tripeptide in alhomycin has not been resolved. According to Maeher and Pitcher (29) albo-mycin can have only one serine residue, and hence a revision of the structure proposed by Turkova et al. (30) may be required.
