title: Cloning and expression of Thiobacillus versutus aspartate-semialdehyde dehydrogenase gene in Escherichia coli.
abstract: The Thiobacillus versutus asd gene coding for aspartate-semialdehyde dehydrogenase was cloned in Escherichia coli cells using pBR322 as a vector. The gene was expressed independently of its orientation, suggesting that E. coli RNA polymerase recognized T. versutus promoter sequence. The T. versutus DNA coded protein, of the molecular weight 44,000, was identified by the analysis of the proteins produced by minicells.
