Figure 1From: High-quality production of human α-2,6-sialyltransferase in Pichia pastoris requires control over N-terminal truncations by host-inherent protease activities Structural domains of human ST6Gal-I (data base entry P15907). Italics: cytosolic domain (aa 1–9). Bold: transmembrane domain (aa 10–27). Underlined: stem-region (aa 28–62). Bold and Italics: potential N-glycosylation sites. N-termini of truncated variants are indicated by a grey arrow.Back to article page
