Middle operon regulator, Mor [109659] (1) contains extra N-terminal dimerisation subdomain: alpha-hairpin (27-72) dimer is a four-helical bundle with right-handed twist
Alr1493-like [140216] (1) Pfam 04255; DUF433; contains extra C-terminal helix and N-terminal dimerisation interlock subdomain (scop_cf 47405)
Nanomeric phage protein-like [140219] (1) contains additional N and C-terminal helices and the C-terminal beta-strand forming an intersubunit beta-barrel with a channel
RpiR-like [158263] (1) Pfam 01418; contains two extra helices, one at each termini; overall arrangment of five helices is similar to the helical core of the lambda integrase-like catalytic domain (scop_fa 56350)
DNA-binding protein Mj223 [81690] (1) homologous to the MarR-like family in the DNA-binding region but dimerizes differently through the N- and C-terminal helical extensions to the common fold
Penicillinase repressor [101016] (4) homologous to the MarR-like family in the DNA-binding region but has a different dimerisation subdomain
Transcription factor MotA, activation domain [46813] (1) The N- and C-terminal helical extensions to the common fold form the dimer interface (distinct from that of ArsR-like family)
PF1790-like [140286] (1) sequence similarity to PH1932 in the N-terminal domain; the C-terminal domain provides new dimerisation interface made of a beta-hairpin and a coiled coil
HxlR-like [140304] (5) 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)
STY4665 C-terminal domain-like [158308] (1) Pfam 07515; DUF1528; the "wing" hairpin, linker between helices 1 and 2 and the C-terminal tail together form an open beta-sheet barrel
PSPTO2686-like [158311] (1) Pfam 04337; DUF480; duplication: two "winged helix" domains are tightly packed "back-to-back" about pseudo twofold axis
YlxM/p13-like [109706] (2) Pfam 04297; UPF0122 structural and detectable sequence similarity to Sigma4 domain; contains extra C-terminal all-alpha oligomerization subdomain; forms different, helix-swapped dimers
KorB DNA-binding domain-like [109709] (1)
contains HTH motif in the common core; also contains extra N-terminal helix and C-terminal subdomain of 4 helices (left-handed superhelix) uperfamily
