the spermidine-preferential uptake system consists of 4 proteins, that are all necessary for spermidine uptake: PotA, PotB, PotC and PotD. The calculated molecular weights are 43000 Da for PotA, 31000 Da for PotB, 29000 Da for PotC and 39000 Da for PotD. The putrescine-uptake system consists of the 4 proteins: PotF, PotG, PotH and PotI. All 4 proteins are necessary for maximal putrescine transport. PotF is a 38000 Da putrescine binding protein, PotG is a 45000 Da membrane-associated ATPase, PotH and PotI are 31000-35000 Da channel-forming proteins |
