What distinguishes an esterase from a lipase: a novel structural approach.

abstract：:Unlike most tonoplast ATPases, the vacuolar ATPase of Acer pseudoplatanus cells (Km = 0.4 mM) was strongly inhibited by vanadate (I50 = 10 microM). The inhibition was non-competitive. Chemicals usually added in the reaction mixture either increase (NH+4, K+) or decrease (Na+, EDTA) the ATPase inhibition. However, thes...
