CC -!- FUNCTION: Catalyzes the dehydration of methylthioribulose-1-phosphate
CC (MTRu-1-P) into 2,3-diketo-5-methylthiopentyl-1-phosphate (DK-MTP-1-P).
CC Functions in the methionine salvage pathway, which plays a key role in
CC cancer, apoptosis, microbial proliferation and inflammation. May
CC inhibit the CASP1-related inflammatory response (pyroptosis), the
CC CASP9-dependent apoptotic pathway and the cytochrome c-dependent and
CC APAF1-mediated cell death. {ECO:0000255|HAMAP-Rule:MF_03116,
