MBD1 is a gene fusion of two genes involved in the methionine salvage pathway: methylthioribulose-1-phosphate dehydratase -mtnB; and 1,2-dihydroxy-3-keto-5-methylthiopentene dioxygenase - mtnD.
These enzymes catalyze non-consecutive steps in the pathway. Interestingly the gene that codes for the intervening enzyme in the pathway, mtnC, is missing from the genome of Tetrahymena. Complementation tests in yeast were used to show that MBD1 from Tetrahymena is able to do in one step what yeast does in three, since it can rescue yeast knockouts of mtnB, mtnC, or mtnD (Salim, Negritto and Cavalcanti 2009).
