description: This family includes includes Protein CHLORORESPIRATORY REDUCTION 42 (CRR42) from Arabidopsis
  thaliana, which is required for both formation and activity of the chloroplast NAD(P)H dehydrogenase
  (NDH) complex of the photosynthetic electron transport chain [[cite:PUB00100355]]. CRR42 functions in
  assembly or stabilization of the NDH complex and it is likely involved, together with CRR1 and CRR6
  in the incorporation of NdhJ, NdhM, NdhK and NdhI into the NDH subcomplex A assembly intermediate (NAI500)
  to produce the complex NAI400 [[cite:PUB00100355]]. This family also includes uncharacterised proteins
  from cyanobacteria.
