of bacterial proteins, such as the chaplin, curli, and tafi proteins
from
Streptomyces
,
Escherichia coli
, and
Salmonella
, respectively,
exhibit similar properties
and serve similar biological functions to
hydrophobins (Chapter 7). However, despite the visual resemblance
of these bacterial protein assemblies to hydrophobin rodlets,
there is little similarity in the
amino acid sequences between these
proteins. This use of the amyloid fibril scaffold in a number of micro-
organisms represents a prime example of functional convergence
found in nature.
