This domain is found in Cellulose Synthase Subunit B (BscB) from Cereibacter sphaeroides and similar sequences predominantly found in bacteria. BscB, involved in bacterial cellulose biosynthesis, is organized into two periplasmic carbohydrate binding domains (CBD-1/2, Pfam:PF03170) and two alpha/beta-domains with similarity with a flavodoxin-fold (FD1 and FD2) [1]. This entry represents FD2.
