EC 5.5.1.25

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.
