摘要:
Dietary compositions, especially cow's milk-based infant formulas, are fortified with bile salt-activated lipase. Methods are provided for feeding newborn and premature infants which include administration of bile salt-activated lipase to increase fat digestion and therefore growth rate. Similarly, a method is provided to treat subjects for inadequate pancreatic enzyme production by administration of bile salt-activated lipase in conjunction with ingestion of fats.
摘要:
The complete structure of human milk BAL cDNA is disclosed. The nucleotide sequences of the cDNA inserts of two clones overlap and together contain 2951 base pairs of BAL cDNA which codes for an open reading frame of 720 amino acid residues between initiation and termination codons. There is a putative signal sequence of 20 residues which is followed by a 61-amino-terminal sequence of BAL. The cDNA sequence also contains a 678-base 5'-untranslated sequence, a 96-base 3'-untranslated region, and a 14-base poly(A) tail. The deduced BAL protein structure contains in the carboxyl-terminal region fourteen repeating units of 11 amino acids each. The repeating units have the basic structure of Pro-Val-Pro-Pro-Thr-Gly-Asp-Ser-Gly-Ala-Pro-, with only minor substitutions. The cDNA is useful for expression of protein, study of structure, function and the effect of modification or deletion or addition of amino acids, including entire repeating units, and as probes for studies involving BAL or related lipases, including rat pancreatic lysophospholipase, cholinesterase, and acetylcholinesterase.

A method is provided to treat subjects for inadequate pancreatic enzyme production by administration of bile salt-activated lipase in conjunction with ingestion of fats. The bile salt-activated lipase is provided in a dosage providing at least 1 mg lipase/2000 mg ingested fat.
