Small genes under sporulation control in the Bacillus subtilis genome.

abstract：:The KRE1 gene of Saccharomyces cerevisiae, sacKRE1, appears to be involved in the synthesis of cell wall beta-glucan. S. cerevisiae strains with mutations in the KRE1 gene produce a structurally altered cell wall (1----6)-beta-glucan, which results in resistance to K1 killer toxin. We isolated the canKRE1 gene from Ca...
