We have partially purified and characterized an 87 kDa gelatinase activity expressed in later stage sea urchin embryos. Cleavage activity was specific for gelatin and no cleavage of sea urchin peristome type I collagen, bovine serum albumin or casein was detected. Magnesium and Zn 21 inhibited the g
