the h+-atpase is electrogenic , apparently of lower capacity , required a lower optimal atp concentration ( 4 microm for the h+-atpase and 500 microm for ( h+-k+ ) -atpase ) , of lower sensitivity to vanadate and sulfhydryl agents such as p-chloromercuribenzoate and n-ethylmaleimide , and insensitive to sch 28,080 , a known competitive inhibitor of ( h+-k+ ) -atpase with respect to k+ .
