Splice sites suggested by EST T44949 are indicated by est . The Arabidopsis AtSAP gene also encodes a senescence-associated protein and is highly regulated during leaf senescence.
Rhodanese proteins catalyze the conversion of thiosulfate and cyanide to sulfite and thiocyanate.
The structure for bovine mitochondrial thiosulfate sulfurtransferase has been solved. The enzyme consists of two domains that share little sequence similarity but have the same structure.
