dddQ

Gene
dddQ
Protein
Dimethlysulfonioproprionate lyase DddQ
Organism
Ruegeria pomeroyi (strain ATCC 700808 / DSM 15171 / DSS-3)
Length
201 amino acids
Function
May act as a dimethlysulfonioproprionate (DMSP) in vitro, releasing dimethyl sulfide (DMS). DMS is the principal form by which sulfur is transported from oceans to the atmosphere (PubMed:20880330). The real activity of the protein is however subject to debate and it is unclear whether it constitutes a real dimethlysulfonioproprionate lyase in vivo (Probable).
Similarity
Belongs to the non-heme iron-dependent dioxygenase family.

Protein
Dimethlysulfonioproprionate lyase DddQ
Organism
Ruegeria lacuscaerulensis (strain DSM 11314 / KCTC 2953 / ITI-1157)
Length
192 amino acids
Function
Able to cleave dimethlysulfonioproprionate (DMSP) in vitro, releasing dimethyl sulfide (DMS). DMS is the principal form by which sulfur is transported from oceans to the atmosphere (PubMed:24395783, PubMed:24967457). The real activity of the protein is however subject to debate and it is unclear whether it constitutes a real dimethlysulfonioproprionate lyase in vivo: the very low activity with DMSP as substrate suggests that DMSP is not its native substrate (PubMed:24760823).
Similarity
Belongs to the non-heme iron-dependent dioxygenase family.
