Abstract

cca Mutants of Escherichia coli K12 have altered levels of tRNA nucleotidyl-transferase activity. The cca locus has been located at minute 59.4 of the E. coli linkage map. It is cotransduced with tolC but not with argG, and is the earliest known marker transferred by Hfr strain KL14. The proximity of the tolC locus to the integrated sex factor in Hfr strain KL14 may be useful for mapping sex factor mutations by transduction.

摘要

大肠杆菌K12的cca突变体具有改变的tRNA核苷酸转移酶活性水平。cca基因座位于大肠杆菌连锁图谱的59.4分钟处。它与tolC共转导,但不与argG共转导,并且是Hfr菌株KL14转移的最早已知标记。在Hfr菌株KL14中,tolC基因座与整合的性因子接近,这可能有助于通过转导来定位性因子突变。
