Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
For reconstitution add 182 µL of sterile water.
Specific Species Reactivity: Arabidopsis thaliana
FtsH9 encodes a chloroplast-targeted, membrane-anchored AAA+ metalloprotease that localizes predominantly to the chloroplast envelope. It is synthesized as a nuclear-encoded precursor with an N-terminal chloroplast transit peptide, followed by one or more N-terminal transmembrane helices that anchor the protein in the envelope and position a large stromal-facing catalytic region. The mature protein is a member of the M41 FtsH family and is characterized by a central AAA+ ATPase module (with conserved Walker motifs required for ATP-dependent substrate engagement/unfolding) coupled to a C-terminal Zn2+-dependent protease domain containing the canonical HEXXH metal-binding motif. Comparative analyses of Arabidopsis plastid FtsH proteases indicate that, unlike the abundant thylakoid FtsH complexes primarily implicated in photosystem II repair, FtsH9 belongs to an envelope-associated subgroup (including FtsH7/9/12 and related inactive FtsHi proteins), and its specific in vivo substrates and physiological role remain incompletely defined; nonetheless, its domain architecture strongly supports a role in ATP-dependent quality control and/or regulated turnover of chloroplast envelope proteins, contributing to proteostasis at the organelle boundary.
