aThe copy numbers per cell of the products of various metal-resistance determinants are given for C. metallidurans strain CH34 cultivated without added substance (CH34_0), metal-shocked (CH34_M) and metal-starvation conditions (CH34_E) with the mean values and deviations. Numbers without deviations indicate proteins determined just once in the respective triplicate determination. The copy numbers are followed by the ratios Q and the distance value D for the comparison of CH34_M and of CH34_E with CH34_0. These values were not provided when the respective protein could not be measured in CH34_0. NF, not found. Not found in any of the cells were the products of the genes cadA, pbrA, and czcD. The copper-exporting PIB1-type ATPase CtpA1 (Rmet_2379) was found only once with 917 copies in nonchallenged AE104 cells.
