Abstract
The genotypes and the main phosphorylation levels of beta-casein of goat milk were studied using RP-HPLC/ESI-MS. A new variant of caprine beta-casein named E has been characterized using RP-HPLC/ESI-MS, MALDI-MS and NanoESI MS/MS methods. Its sequence differed from that of variant A in the mono amino acid substitution D47 --> Y47, which resulted in a 48 Da experimental mass difference between them. The calculated molecular mass of the new variant E 6 P was estimated as 23,869 Da. Its phosphorylation pattern was similar to that of variant A, the most abundant types being those with 5 and 6 P in similar quantities.Entities:
