Part A: Biosynthesis and posttranslational modifications of recombinant proteins

Biosynthesis of cytosolic and secretory proteins
Protein folding, quality control and co-factor incorporation (heme, flavin) within the cytosol and the secretory pathway
Posttranslational protein modifications I: N- and O-glycosylation in biotechnologically relevant organisms
Posttranslational protein modifications II: role of glycosylation in targeting, turnover and immunology of recombinant proteins
Posttranslational protein modifications III: phosphorylation, hydroxylation, carboxylation, acetylation, methylation etc. and their functional relevance
Analysis of post-translational modifications I: chromatographic and electrophoretic techniques
Analysis of post-translational modifications II: mass spectrometry
Proteomics: concepts and recent developments

Part B: Intracellular protein trafficking and its biotechnological relevance

General concepts of intracellular transport processes
The secretory pathway I: the endoplasmic reticulum
The secretory pathway II: the Golgi apparatus
Protein secretion in yeasts and filamentous fungi
Regulated and non-canonical secretion
Endocytosis, endosomes and lysosomes
Intracellular protein degradation pathways
Protein storage organelles
