|MadSci Network: Biochemistry|
This is not my field but a quick search of the literature uncovered a couple of pointers. (Note- Most of the work seems to have been done in yeast.) Chiten can be linked to mannoproteins via a beta1-6 glucan link, see J. Bacteriology 179:6279 (1997) The terminal reducing residue of a chitin chain can be attached to the non-reducing end of a beta(1->3)-glucan chain by a beta(1->4) linkage; see J. Biol. Chem. 270:1170 (1995). Another relevant sounding reference that I haven't investigated is Biochem. Soc. Trans. 25:200 (1997). Thus, it sounds as though chitin tends to be crosslinked to various other cell wall components. Browse Medline, keyword "chitin", using PubMed, or the access means of your choice to find other similar papers. In addition, a search through other databases may yield more information. (Note, if you are at the graduate school level, you might consider answering questions here rather than asking them. You also should get your literature searching skills up to speed.)
