Fig. 1From: PySupercharge: a python algorithm for enabling ABC transporter bacterial secretion of all proteins through amino acid mutationABC Transporter Proteins. Structure of the ABC transporter protein in the bacterial inner membrane. The extracellular space (and by extension, the periplasmic space) is less negative than the cytoplasm [26]. This ABC transporter can be used in extracellular secretion-based protein productionBack to article page
