... a rapid phase, regardless of the presence of LlCBP3 3A. In the presence of LlCBP3 3A, the fastinitial phase was maintained longer than in the absence of LlCBP3 3A, indicating that LlCBP3 3A acts ... CBP21 and CHB1.Degradation of a- and b-chitin The degradation rates of a- and b-chitin were assayedwith LlChi1 8A in the presence or absence of LlCBP3 3A. As both chitin variants, and especially a- chitin, ... chains are degraded by bothendochitinases, that attack the chitin chain randomly,and exochitinases, that attack the chitin chains fromeither the reducing or nonreducing end [6,7]. As endo-acting...
