TauD protein domain
protein family

In molecular biology, TauD refers to a protein domain that in many enteric bacteria is used to break down taurine (2-aminoethanesulfonic acid) as a source of sulfur under stress conditions. In essence, they are domains found in enzymes that provide bacteria with an important nutrient.
Function
This protein family consists of TauD/TfdA taurine catabolism dioxygenases. The Escherichia coli tauD gene is required for the utilization of taurine (2-aminoethanesulfonic acid) as a sulfur source and is expressed only under conditions of sulfate starvation. TauD is an alpha-ketoglutarate-dependent dioxygenase catalyzing the oxygenolytic release of sulfite from taurine. The 2,4-dichlorophenoxyacetic acid/alpha-ketoglutarate dioxygenase from Burkholderia sp. (strain RASC) also belongs to this family. TfdA from Ralstonia eutropha (Alcaligenes eutrophus) is a 2,4-D monooxygenase.
Structure
This structure has a number of alpha helices and beta sheets.
“TauD protein domain” enters the record as protein family. Crown Archives preserves that source wording while asking what TauD, protein and domain can confirm, complicate or overturn.
Why this record matters
“TauD protein domain” is worth following because a concise public description often conceals a longer documentary argument. Here, TauD, protein and domain provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q7688599. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
