As the tryptic susceptibility of rhLF cDNA differs from natural hLF and rhLF gen (Fig. 2), we decided to study the role of N-linked glycosylation in the protection of hLF in more detail, and also ... absence of glycosylation in rhLF- Gln138/479, which has the naturally occurring Gly404, does not lead to increased tryptic susceptibility of the rhLF- Gln138/479 molecules. Taken together, the results ... [3] and bactericidal activity by destabilization of the cell wall [4,5]. Anti-inflammatory actions of LF include inhibition of hydroxyl-radical forma- tion [6], of complement activation [7] and of...
