FAQ: What is the difference between β1–4 Galactosidase and β1–4 Galactosidase S?
β1–4 Galactosidase (NEB# P0730) is cloned from Bacteroides fragilis; whereas, β1–4 Galactosidase S (NEB# P0745) is cloned from Streptococcus pneumonia. Both enzymes cleave β1–4 linked galactose residues. The two versions of the enzyme have identical activity, specificity and concentration.
