Which of the statements about endoglucanases and cellobiohyd

Which of the statements about endoglucanases and cellobiohydrolases hydrolyzing glycoside bonds is TRUE? (more than one answer may be correct)

endoglucanases and cellobiohydrolases bind cellulose molecules (substrate).

endoglucanases produce exclusively cellobiose as the result of catalysis.

cellobiohydrolases produce exclusively cellobiose as the result of catalysis.

endoglucanases and cellobiohydrolases catalyze the identical glycoside bonds.

Solution

Answer:

It is true that both endoglucanases and cellobiohydrolases binds on cellulose molecule and endoglucanases are having selective catalytic domain (namely CBM37 in R albus). However, cellobiohydrolases are not well known for the catalytic function on substrate molecule. So, a and b are correct answer.
