HydA | Iron-hydrogenase HydA1/HydA2

In Chlamydomonas HydA is present in low levels of 1 µg/liter of culture. Therefore, an induction of cells by anaerobic adaptation or sulfur depravation (10 x higher amount than with anaerobic adaptation) is necessary for successful detection using this antibody. Methods of HydA induction are described in Hemschemeier et al. 2009.To detect HydA1/A2 in Chlamydomonas extracts amount loaded per well corresponds to 2 µg of chlorophyll for sulfur deprived cells, where relatively much HydA1 is synthesized or corresponds to 2-4 µg of artificially anaerobic induced cultures, where the HydA1 protein level is lower. This antibody is recognizing 1 ng of recombinant HydA protein.,HydA1 (497aa) has a calculated MW of 53.1 kDa, but this is including the signal peptide, which gets cleaved off. The protein without TP has a calculated MW of 47.5 kDa and runs according to its size at about 48 kDa.HydA2 (505aa) has a calculated MW of 53.7 kDa, but this is including the signal peptide, which gets cleaved off. The protein without TP can only be estimated, since the cleavage site is known only from in silico analysis. It has a calculated MW of 47.3 kDa and should run in the gel also according to its size.This antibody is binding recombinant HydA1/2 protein.

Iron hydrogenase HydA2 catalyzes reversible oxidation of hydrogen molecules. In chlamydomonas, the amount of this protein is lower, at 1 microgram per liter of culture. Synonyme: HYD1/1
