靶點(diǎn)詳情

  • 功能：
    Cell wall formation. Synthesis of cross-linked peptidoglycan from the lipid intermediates. The enzyme has a penicillin-insensitive transglycosylase N-terminal domain (formation of linear glycan strands) and a penicillin-sensitive transpeptidase C-terminal domain (cross-linking of the peptide subunits).
  • 基因功能參考文獻(xiàn)：
    1. crystal structures of E. coli PBP1b bound to multiple different beta-lactams in the transpeptidase active site and complement these data with gel-based competition assays to provide a detailed structural understanding of its inhibition. Taken together, these biochemical and structural data allow us to propose new insights into inhibition of both enzymatic domains in PBP1b. PMID: 27899450
    2. findings show that PBP1b is vital for competitive survival of E. coli during extended stationary phase; loss of PBP1b leads to the stationary phase-specific competition defective phenotype and causes cells to become more sensitive to osmotic stress PMID: 16958852
    3. the X-ray crystal structure of the bifunctional transglycosylase penicillin-binding protein 1b (PBP1b) from Escherichia coli in complex with its inhibitor moenomycin to 2.16-A resolution was determined. PMID: 19458048
  • 亞細(xì)胞定位：
    Cell inner membrane; Single-pass type II membrane protein.
