摘要: The instant disclosure provides, among other things, novel nuclease proteins (enzymes), novel nuclease compositions and protein preparations thereof, recombinant polynucleotides (DNA) encoding such nuclease proteins, recombinant host cells expressing and producing one or more nuclease proteins (optionally co-expressing one or more proteins of interest) and the like. More particularly, the nuclease proteins (enzymes) of the instant disclosure are particularly useful in mitigating DNA contamination, such as contaminating DNA present in a fermentation broth in which microbial host cells have been fermented, contaminating DNA present in recovered proteins of interest, contaminating DNA present in protein preparations, and the like.

摘要: The present invention relates in general to bacterial cells having a genetic alteration that results in increased expression of a protein of interest and methods of making and using such cells. Aspects of the present invention include Gram positive microorganisms, such as Bacillus species, having a genetic alteration that modifies activity of a protein encoded by the ykf operon and results in enhanced expression of a protein of interest.

摘要: The present disclosure is generally related to modified Gram positive bacterial cells producing increased amounts of one or more protein(s) of interest and modified Gram positive bacterial cells having increased genetic competency. Thus, certain embodiments of the disclosure are directed to modified Gram positive bacterial cells expressing an increased amount of a protein of interest, relative to an unmodified (parental) Gram positive bacterial cell expressing the same protein of interest, wherein the modified bacterial cell comprises at least one mutation in a rpoC gene encoding a variant RNA-polymerase (RNAP) β′-subunit polypeptide. In certain embodiments, the rpoC gene encoding the variant β′-subunit polypeptide is integrated into the chromosome of the modified cell. In other embodiments, the rpoC gene encoding the variant β′-subunit polypeptide is comprised on an extrachromosomal plasmid introduced into the modified cell. In other embodiments, the disclosure is directed to competent Bacillus host cells comprising at least one copy of a nucleic acid construct encoding a modified rpoC polypeptide comprising 90% sequence identity to SEQ ID NO: 8 and an aspartic acid to glycine substitution at position 796 of SEQ ID NO: 8, wherein the polynucleotide encoding the rpoC polypeptide is foreign to the Bacillus host cell that was non-competent prior to the introduction of the first nucleic acid construct.
