FunFam 88046: Probable diguanylate cyclase YegE

There are 3 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Cyclic-guanylate-specific phosphodiesterase. [EC: 3.1.4.52]
Cyclic di-3',5'-guanylate + H(2)O = 5'-phosphoguanylyl(3'->5')guanosine.
  • Inhibited by Ca(2+) and Zn(2+).
  • Linearizes cyclic di-3',5'-guanylate, the product of EC 2.7.7.65 and an allosteric activator of EC 2.4.1.12 rendering it inactive.
  • It is the balance between these two enzymes that determines the cellular level of cyclic di-3',5'-guanylate.

Diguanylate cyclase. [EC: 2.7.7.65]
2 GTP = 2 diphosphate + cyclic di-3',5'-guanylate.
  • Can be activated by BeF3, a phosphoryl mimic, which results in dimerization.
  • Dimerization is required but is not sufficient for diguanylate- cyclase activity.
  • Cyclic di-3',5'-guanylate is an intracellular signaling molecule that controls motility and adhesion in bacterial cells; it was first identified as having a positive allosteric effect on EC 2.4.1.12.

Histidine kinase. [EC: 2.7.13.3]
ATP + protein L-histidine = ADP + protein N-phospho-L-histidine.
  • This entry has been included to accommodate those protein-histidine kinases for which the phosphorylation site has not been established (i.e. either the pros- or tele-nitrogen of histidine).
  • A number of histones can act as acceptor.
