Ekso-1,4-beta-D-glukozaminidaza (EC 3.2.1.165, CsxA, GlcNaza, eksohitozanaza, GlmA, ekso-beta-D-glukozaminidaza, hitozan ekso-1,4-beta-D-glukozaminidaza) je enzim sa sistematskim imenom hitozan ekso-(1->4)-beta-D-glukosaminidaza.[1][2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju
- hidroliza hitozana ili hitozan oligosaharida čime se sukcesivno odvajaju D-glukozaminski ostataci sa neredukujućeg kraja
Hitozan je parcijalno ili totalno N-deacetilisan hitinski derivat koji je prisutan u ćelijskim zidovima pojedinih fitopatogenih gljiva.
