Cytoplasmic glycome Whereas glycosylation occurs predominantly in the secretory compartments, formation of the precursors for these pathways generally originates in the cytoplasm, and the cytoplasm ... DIF is made by a three step biosynthetic pathway, in which a 12-carbon po lyke- tide is assembled by the StlB polyketide synthase, then successively chlorinated...

... basis on immunhis- tochemical analysis of the expression of proteins in tissues, which is only semi-quantita- tive. However, due to the limitations of any immunohistochemical analysis of tissues, ... An increased amount of collagen type III in scar may indicate either an enhanced synthesis or a delayed degradation of collagen type III. It is reasonable that any disturbed matura- t...
