An essential role for actA in acid tolerance of Rhizobium meliloti.

Microbiology (Reading, England) - 1 Mar 1996

Tiwari Ravi P, Reeve Wayne G, Dilworthan Michael J, Glenn Andrew R

Abstract excerpt

The actA gene, which is disrupted by Tn5 in the acid-sensitive mutant of Rhizobium meliloti TG2-6, was cloned and sequenced. It encodes a protein of 541 amino acids with a calculated molecular mass of 57,963 Da and an estimated pl of 9.0. The ActA protein sequence has 30% identity, and much highe...
