The cysA471 mutation was isolated by Tully (1976) as conferring resistance to chromate, the cysZ474 mutation arose spontaneously and simultaneously with a ptsI mutation, (it may be the result of an inversion with ends in these two genes). The mapping of the genes (see above, Table 3) shows that cysA and cysZ lie on opposite sides of ptsI. We therefore investigated the biochemical nature of the mutations.", }
