Penicillin-binding proteins in Bacillus subtilis mutants [PDF]

Antimicrobial Agents and Chemotherapy, 1982
The penicillin-binding proteins (PBPs) from mutants of Bacillus subtilis were studied and related to morphology. In a previously described cloxacillin-resistant mutant of B. subtilis strain Porton, PBP 2a had an altered mobility by sodium dodecyl sulfate gel electrophoresis and was present in increased amounts.

Detection and characterization of Sp1 binding activity in human chondrocytes and its alterations during chondrocyte dedifferentiation. [PDF]

, 1997
We have detected DNA binding activity for a synthetic oligonucleotide containing an Sp1 consensus sequence in nuclear extracts from human chondrocytes. Changes in the levels of Sp1 oligonucleotide binding activity were examined in nuclear extracts from ...

The porin and the permeating antibiotic: A selective diffusion barrier in gram-negative bacteria [PDF]

, 2008
Gram-negative bacteria are responsible for a large proportion of antibiotic resistant bacterial diseases. These bacteria have a complex cell envelope that comprises an outer membrane and an inner membrane that delimit the periplasm.

Diversity of Penicillin-binding Proteins [PDF]

Journal of Biological Chemistry, 2007
Antibiotic-resistant Staphylococcus aureus is a major concern to public health. Methicillin-resistant S. aureus strains are completely resistant to all β-lactams antibiotics. One of the main factors involved in methicillin resistance in S. aureus is the penicillin-binding protein, PBP2a.

Identification of Treponema pallidum penicillin-binding proteins [PDF]

Journal of Bacteriology, 1987
Penicillin-binding proteins of 180, 89, 80, 68, 61, 41, and 38 kilodaltons were identified in Treponema pallidum (Nichols) by their covalent binding of [35S]benzylpenicillin. Penicillin-binding proteins are localized in the plasma membranes of many bacterial species and may serve as useful markers for determining plasma membrane intactness in T ...

Affinity of cefoperazone for penicillin-binding proteins [PDF]

Antimicrobial Agents and Chemotherapy, 1980
Cefoperazone (T-1551, CFP) a new semisynthetic cephalosporin, has a broad spectrum of antibacterial activity. We investigated the affinity of CFP to penicillin-binding proteins (PBPs) and the inhibition of peptidoglycan synthesis by CFP. CFP had high affinities for Escherichia coli PBP-3, -1Bs, -2, and -1A, in descending order, and low affinities for ...

A combined computational-experimental approach to define the structural origin of antibody recognition of sialyl-Tn, a tumor-associated carbohydrate antigen. [PDF]

, 2018
Anti-carbohydrate monoclonal antibodies (mAbs) hold great promise as cancer therapeutics and diagnostics. However, their specificity can be mixed, and detailed characterization is problematic, because antibody-glycan complexes are challenging to ...
