Abstract

See full text

Proteins with Hyp-glycosylation are more likely to be secreted in plant cells at high levels than those without. Methods are disclosed for the prediction of Pro-hydroxylation and Hyp-glycosylationsites in proteins. Such methods can be used to identify (1) proteins which, without modification, are predisposed to develop Hyp-glycosylation, if expressed in plant cells, and (2) modifications (especially substitution mutations) which increase the propensity of a protein to develop Hyp-glycosylation, with a view to high level or increased secretion. It is also possible to determine empirically whether a particular protein will undergo Hyp-glycosylation suitable for the desired level of secretion in plant cells. Both modified proteins, and methods for the expression and secretion of predisposed and modified proteins, are claimed.
