We proposed that the 3-hydroxypropionate/4-hydroxybutyrate cycle
might be important in global carbon cycling based on the abundance
of related autotrophic Crenarchaea in the ocean and the high
number of gene sequences for a key enzyme of the cycle. Here,
we counter the specific criticisms raised by Ettema and Andersson.
