S. Moreau et al., HYDROLYSIS OF HEN EGG-WHITE OVOMUCIN, ZEITSCHRIFT FUR LEBENSMITTEL-UNTERSUCHUNG UND-FORSCHUNG A-FOOD RESEARCH AND TECHNOLOGY, 205(5), 1997, pp. 329-334
This paper reports on the solubilization of ovomucin by hydrolysis. Th
is glycoprotein can easily be obtained by precipitation but the precip
itate itself is not soluble in ordinary buffers, Flavourzyme, a protea
se/peptidase complex, enables the solubilization of ovomucin in 1 h an
d the hydrolysis of the soluble materials. These compounds were studie
d by HPLC gel permeation, electrophoresis and an amino acid analyser i
n order to define their molecular weight, the presence of glycans and
the liberation of free amino acids. High-molecular-weight glycosylated
materials (>94,000 Da) and one glycopeptide (38,100 Da) were detected
, Free amino acids (all amino acids are represented) and peptides (fro
m 34,400 to 20,800 Da) were also released in the solution.
