K,-cells from Drosophila melanogaster, grown under serum-free conditions, produce two p-hexosaminidases and secrete these enzymes into the medium. The two enzymes were separated by DEAE-exchange chromatography. According to their substrate specificities one enzyme is a f3-N-acetyl-D-glucosarninidase
Kc-cells from Drosophila produce two different beta-D-hexosaminidases, a beta-N-acetyl-D-glucosaminidase (E.C.3.2.1.30) and a beta-N-acetyl-D-hexosaminidase (E.C.3.2.1.52), which are also secreted into the medium. The Mr of both enzymes is about 126,000 +/- 9,700; the S-values are 8.37 +/- 0.44. Bot
