9.B.34.1.1









The diguanylate cyclase (GGDEF domain-containing) protein with N-terminal "transporter" or "receptor" domain with 6 TMSs, Dge1 (Mansour et al., 2007).

Bacteria
Deinococcota
Dge1 of Deinococcus geothermalis (Q1J0W6)
9.B.34.1.2









Transmembrane protein of 371 aas and 5 N-terminal TMSs. It is a positive regulator of cellulose biosynthesis, AdrA (Zogaj et al. 2001).

Bacteria
Pseudomonadota
AdrA of E. coli
9.B.34.1.3









Putative diguanylate cyclase of 396 aas, with 6 N-terminal TMSs

Bacteria
Cyanobacteriota
Diguanylate cyclase of Arthrospira platensis (Spirulina platensis)
9.B.34.1.4









Probable diguanylate cyclase of 564 aas with 1 N-terminal TMS and 1 central TMS, YedQ.  May play a regulatory role in cellulose synthase activity (Hu et al. 2015).

Bacteria
Pseudomonadota
YedQ of E. coli
9.B.34.1.5









Diguanylate cyclase (GGDEF) domain-containing protein of 906 aas and 10 N-terminal TMSs.

Bacteria
Bacillota
DGC of Bacillus cereus
9.B.34.1.6









Putative diguanylate cyclase (GGDEF) with 272 aas and maybe 3 TMSs, two N-terminal, and one near the C-terminus.  This protein is encoded within an operon that also codes a putative phenylpropeneoid ABC-type transporter (TC# 3.A.1.4.11) and a putative phenylacetate-CoA ligase (Q6N8W5).

Bacteria
Pseudomonadota
Putative diguanylate cyclase of Rhodopseudomonas palustris
9.B.34.1.7









Hybrid sensor histidine kinase/response regulator of 802 aas and 6 N-terminal TMSs with homology to members of family 9.B.34 in the TM domain.

Bacteria
Pseudomonadota
SK-RR of Ahrensia sp.
9.B.34.1.8









EAL domain-containing protein of 878 aas and 6 N-terminal TM

Bacteria
Pseudomonadota
EAL protein of Pseudomonas zhaodongensis
9.B.34.1.9









Diguanylate cyclase/phosphodiesterase of 806 aas and 10 N-terminal TMSs.

Bacteria
Actinomycetota
diGC of Mycolicibacterium rhodesiae
