	Problem XXIX / 16 Methylmalonyl~CoA-pathway: enzymes

	The ratio of Propionate_formed : Acetate_formed is 2:1 for the fermentation of Lactate via the Methylmalonyl~CoA-pathway by Propionibacterium sp. Fill in the names of the enzymes which catalyze the 12 steps of the pathway. The names and the formulas of the intermediates are shown in the table below.
