Family: HxlR-like [140304]
Pfam 01638; DUF24; the N- and C-terminal helical extensions to the common fold form the dimer interface similar to that of the ArsR-like family (scop_fa 46801)
Protein: Hypothetical protein PA1607 [140307]
includes extra C-terminal SH3-like subdomain, which is segment-swapped in the dimer
