Myohemerythrin- a four helix bundle domain
2
Diiron coordination in myohemerythrin
3
Replication Origin Protein (rop 2-chain four
helix bundle)
4
Lac repressor (4-chain four helix bundle)
5
Gamma-crystallin - a pair of beta
sandwiches (four beta-sheets, each containing
Greek key motifs)
6
Porins come in a wide variety of flavors and
are trimeric in their assembly
7
An eight-stranded beta-barrel from
triose-phosphate isomerase Contains
beta-alpha-beta motifs.
8
Domain on the right is an eight-stranded barrel
from RuBisCo. Note inhibitor being bound by
loops, not barrel.
9
Carboxypeptidase has 8-stranded beta-sheet made
up of beta-alpha-beta motifs
10
Substrate is partially buried in crevice
