Isolation and characterization of the Escherichia coli htrD gene, whose product is required for growth at high temperatures.

abstract：:Early log-phase cells of Mycoplasma gallisepticum A5969 were synchronized by holding in Eagle minimal essential medium (MEM) for 2 h. When transferred out of MEM into tryptose medium, the cells exhibited synchronous growth. Deoxyribonucleic acid (DNA) synthesis proceeded continuously during this growth but stopped dur...
