| cellulase activity of leishmania major in the sandfly vector and in culture. | the secretion of cellulose-degrading enzymes by leishmania promastigotes in culture and in the sandfly vector was demonstrated. two types of activity of cellulase enzyme-complexes were measured: endoglucanases, which randomly cleave cellulose chains and cellobioydrolases, which remove cellobiose from the nonreducing end of the molecule. the assays demonstrated that enzymes with these activities were secreted into the culture medium by leishmania major, l. donovani, and l. braziliensis. these act ... | 1997 | 9183709 |
