aObservations based on annotation.

bClassification written in bold indicates that it is inside the α-operon.

cThe duplicates of the zinc-binding r-proteins S14, L28, L33 sit together in the genome.

dResulting from the duplication of the whole α-operon.

eAverage value of the percent identities of the two pairs of in-operon and out-of-operon copies.

f A. metalliredigens and C. acetobutylicum have 2 copies of the C-(V) form.

gResulting from the duplication of the entire s10-spc and α-operon.
