Kuroki Y, et al. (2002) Cloning and characterization of vmaA, the gene encoding a 69-kDa catalytic subunit of the vacuolar H+-ATPase during alkaline pH mediated growth of Aspergillus oryzae. FEMS Microbiol Lett 209(2):277-82
Abstract: Screening of a cDNA library constructed under alkaline pH mediated growth of Aspergillus oryzae implicated a vacuolar H(+)-ATPase gene (vmaA) as a putative candidate involved in alkaline pH adaptation. A. oryzae vmaA genomic DNA extended to 2072 bp including three introns and encoded a protein of 605 amino acids. VmaAp was homologous to Vma-1p from Neurospora crassa (71%), Vma1p from Saccharomyces cerevisiae (69%) and ATP6A2 from human (49%). The vmaA cDNA complemented S. cerevisiae V-ATPase disrupted strain (Deltavma1) was viable at alkaline pH 8.0 and in the presence of CaCl(2) (100 mM). Northern analysis revealed an enhanced expression of vmaA during growth of A. oryzae in alkaline medium (pH 10.0). The A. oryzae vmaA disruptant exhibited abnormally shrunken vacuoles and hyphal walls at pH 8.5 and a growth defect at pH 10.0, implicating an alkaline pH stress responsive role for vmaA in A. oryzae.
