Bile-salt stimulated lipase (BSSL) may comprise amino acids 1-722, 1-535, 1-278, 1-341, 1-409, 1-474, 279-341, 279-409, 279-474, 342-409, 342-474 or 536-722 of the sequence given at the end. Also claimed are (1) a functionally equivalent variant or mutant of BSSL; (2) a DNA sequence (I) encloding BSSL, comprising nucleotides 151-2316, 151-1755, 151-985, 151-1172, 151-1376, 151-1574, 986-1172, 986-1376, 986-1574, 1173-1376 or 1173-1574 of the sequence given in the specification; (3) a vector comprising (I); and (4) a host organism transformed with the vector of (3); and (5) an infant food formulation comprising BSSL. Pref. BSSL may be in combination with one or more of the direct repeats of the sequence given in the specification. BSSL may posses Met as additional N-terminal amino acid.
