D-Allose catabolism of Escherichia coli: involvement of alsI and regulation of als regulon expression by allose and ribose.

abstract：:The obligate psychrophilic yeasts Torulopsis psychrophila, T. austromarina, Leucosporidium frigidum, L. gelidum, and L. nivalis were obligate aerobes and were unable to grow anaerobically. In contrast, the obligate thermophilic yeasts T. bovina, T. pintolopesii, Candida slooffii, and Saccharomyces telluris were facult...

abstract：:The ability to restart broken DNA replication forks is essential across all domains of life. In Escherichia coli, the priA, priB, priC, and dnaT genes encode the replication restart proteins (RRPs) to accomplish this task. PriA plays a critical role in replication restart such that its absence reveals a dramatic pheno...
