This protocol describes the heterologous expression and purification of proteins related to anoxic hydrogen production of Chlamydomonas reinhardtii (Noth et al., 2013). For this, the bacterial expression hosts Escherichia coli BL21 (DE3) ΔiscR (Akhtar MK et al., 2008) and Clostridium acetobutylicum ATCC 824 are used, which are grown either aerobic or anaerobic with glucose. Two standard chromatographic methods for purification were applied using His- and StrepII-tagged proteins (Figure 1). All procedures have been performed in an anaerobic tent to avoid the access of oxygen.
