ID   PALST_EUGGR             Reviewed;        1019 AA.
AC   P84739; Q2P9M8;
DT   10-JAN-2006, integrated into UniProtKB/Swiss-Prot.
DT   18-APR-2006, sequence version 2.
DT   25-MAY-2022, entry version 62.
DE   RecName: Full=Photoactivated adenylate cyclase subunit alpha-like protein ST-;
GN   Name=pacA {ECO:0000312|EMBL:CAJ57396.1};
OS   Euglena gracilis.
OC   Eukaryota; Discoba; Euglenozoa; Euglenida; Spirocuta; Euglenophyceae;
OC   Euglenales; Euglenaceae; Euglena.
OX   NCBI_TaxID=3039;
RN   [1] {ECO:0000305}
RP   NUCLEOTIDE SEQUENCE [MRNA], AND SUBCELLULAR LOCATION.
RC   STRAIN=ST- {ECO:0000269|PubMed:16121285};
RX   PubMed=16121285; DOI=10.1039/b502002f;
RA   Ntefidou M., Haeder D.-P.;
RT   "Photoactivated adenylyl cyclase (PAC) genes in the flagellate Euglena
RT   gracilis mutant strains.";
RL   Photochem. Photobiol. Sci. 4:732-739(2005).
CC   -!- SUBUNIT: Heterotetramer of two alpha and two beta subunits.
CC       {ECO:0000250|UniProtKB:Q8S9F2}.
CC   -!- SUBCELLULAR LOCATION: Cell projection, cilium, flagellum
CC       {ECO:0000269|PubMed:16121285}.
CC   -!- MISCELLANEOUS: The ST- strain is deficient in phototaxis. It is not
CC       known if this is due to defective adenylate cyclase activity or
CC       defective BLUF domains in this protein. In wild-type E.gracilis,
CC       photoactivated adenylate cyclase is found in the paraxonemal bodies
CC       (PABs). PABs are absent from this strain.
CC   -!- SIMILARITY: Belongs to the adenylyl cyclase class-4/guanylyl cyclase
CC       family. {ECO:0000255|PROSITE-ProRule:PRU00099}.
