HHsearch alignment for GI: 255764505 and conserved domain: cd04800

>cd04800 CBS_pair_CAP-ED_DUF294_PBI_assoc2 This cd contains two tandem repeats of the cystathionine beta-synthase (CBS pair) domains associated with either the CAP_ED (cAMP receptor protein effector domain) family of transcription factors and the DUF294 domain or the PB1 (Phox and Bem1p) domain. Members of CAP_ED, include CAP which binds cAMP, FNR (fumarate and nitrate reductase) which uses an iron-sulfur cluster to sense oxygen, and CooA a heme containing CO sensor. In all cases binding of the effector leads to conformational changes and the ability to activate transcription. DUF294 is a putative nucleotidyltransferase with a conserved DxD motif. The PB1 domain adopts a beta-grasp fold, similar to that found in ubiquitin and Ras-binding domains. A motif, variously termed OPR, PC and AID, represents the most conserved region of the majority of PB1 domains, and is necessary for PB1 domain function. This function is the formation of PB1 domain heterodimers, although not all PB1 domain pa
