Accepted name: 3,6-anhydro-L-galactonate cycloisomerase
Reaction: 3,6-anhydro-L-galactonate = 2-dehydro-3-deoxy-L-galactonate
Other name(s): 3,6-anhydro-α-L-galactonate lyase (ring-opening); 3,6-anhydro-α-L-galactonate cycloisomerase
Systematic name: 3,6-anhydro-L-galactonate lyase (ring-opening)
Comments: The enzyme, characterized from the marine bacteria Vibrio sp. EJY3 and Postechiella marina M091, is involved in a degradation pathway for 3,6-anhydro-α-L-galactopyranose, a major component of the polysaccharides of red macroalgae.
