Some of the following caracteristics of Nitrite reductase, which one of the is incorrect?

#I Life Science/ Life Sciences Group – I-V
  1. Nitrite is converted into ammonium by NADPH dependent nitrite reductase
  2. It contain two prosthetic groups: an iron–sulfur cluster (Fe4S4) and a specialized heme.
  3. Nitrite (NO2 – ) is a highly reactive, potentially toxic ion immediately transport from the cytosol into chloroplasts in leaves and plastids in roots
  4. Leaf chloroplasts and root plastids contain same type of the nitrite reductase

#SCPH01 Biochemistry

SDS PAGE separate molecules by size because the presence of SDS (sodium dodecyl sulphate) denatures the protein removing 2˚, 3˚ and 4˚ structures (they assume a linear chain) and the SDS coats the molecules giving them a uniform charge/mass ratio. In an experiment (SDS-PAGE) with a discontinuous buffer system following band pattern is obtained
