Popis: The structure of the hydrolyzed product (F-2) with a molecular mass of about 2 kDa released from gamma-polyglutamic acid by the gamma-glutamyl hydrolase YwtD of Bacillus subtilis was analyzed. The results showed that F-2 is an optically heterogeneous polymer consisting of D- and L-glutamic acid in an 80:20 ratio with D-glutamic acid on both the N- and C-terminal sides, suggesting that YwtD is an enzyme that cleaves the gamma-glutamyl bond between D- and D-glutamic acid recognizing adjacent L-glutamic acid toward the N-terminal region.
