Contact dependent growth inhibition (CDI) is the phenomenon where CDI+ bacterial strain (inhibitor) inhibits the growth of CDI-strain (target) by direct cell to cell contact. CDI is mediated by cdiBAI gene cluster where CdiB facilitates the export of CdiA, an exotoxin, on the cell surface and CdiI acts as an immunity protein to protect CDI+ cells from autoinhibition. CdiA-CT, the C-terminal reg...

Inhibition of manganese peroxidase by cadmium was studied under steady-state and transient-state kinetic conditions. CdII is a reversible competitive inhibitor of MnII in the steady state with Ki approximately 10 microM. CdII also inhibits enzyme-generated MnIII-chelate-mediated oxidation of 2,6-dimethoxyphenol with Ki approximately 4 microM. CdII does not inhibit direct oxidation of phenols su...

The title compound, [Cd2(C7H10NS2)4], is a neutral dinuclear cadmium(II) complex bearing four bis N,N-di-allyl-di-thio-carbamate ligands coordinating to two CdII cations. In each of the monomeric subunits, there are four S atoms of two di-thio-carbamate ligands [Cd-S = 2.5558 (3), 2.8016 (3), 2.6050 (3) and 2.5709 (3) Å] that coordinate to one CdII atom in a bidentate mode. The dimers are locat...

Bacterial contact-dependent growth inhibition (CDI) is mediated by the CdiA/CdiB family of two-partner secretion proteins. Each CdiA protein exhibits a distinct growth inhibition activity, which resides in the polymorphic C-terminal region (CdiA-CT). CDI(+) cells also express unique CdiI immunity proteins that specifically block the activity of cognate CdiA-CT, thereby protecting the cell from ...

The title compound, [CdNa2(C8H4O4)2(C3H7NO)(H2O)2] n or [CdNa2(1,3-bdc)2(DMF)(H2O)2] n , is a new CdII-NaI heterobimetallic coordination polymer. The asymmetric unit consists of one CdII atom, two NaI atoms, two 1,3-bdc ligands, two coordinated water mol-ecules and one coordinated DMF mol-ecule. The CdII atom exhibits a seven-coordinate geometry, while the NaI atoms can be considered to be pent...

Cyclic glyoxalcarbohydrazone[(1,2,4,5,8,9,11,12-octaazacyclotetradeca-5,7,12,14tetraene-3,10-dione) = (glyozalcarbzH)2] complexes of Ni II, PdII, CoII, ZnII and CdII of composition M (glyoxalcarbzH)2X2nH2O (M = Ni II, PdII, CoII,ZnII or CdII and X = Cl> , 1/2 SO4 -2 and n = 0,1 or 4) have been isolated by refluxing appropriate metal salts with glyoxal and carbohydrazide in requisite proportion ...

The title compound, {[Cd(C9H11N2S2)2]·C6H7N} n , features two μ2-κ3-di-thio-carbamate ligands each of which chelates one CdII atom, via the S atoms, while simultaneously bridging to another via the pyridyl-N atom. The result is a two-dimensional coordination polymer extending parallel to the ab plane with square channels along the b axis. The CdII atom geometry is based on a distorted cis-N2S4 ...

Xenorhabdus is a bacterial symbiont of entomopathogenic Steinernema nematodes and is pathogenic for insects. Its life cycle involves a stage inside the insect cadaver, in which it competes for environmental resources with microorganisms from soil and the insect gut. Xenorhabdus is, thus, a useful model for identifying new interbacterial competition systems. For the first time, in an entomopatho...

Contact-dependent growth inhibition (CDI) is a mechanism identified in Escherichia coli by which bacteria expressing two-partner secretion proteins encoded by cdiA and cdiB bind to BamA in the outer membranes of target cells and inhibit their growth. A third gene in the cluster, cdiI, encodes a small protein that is necessary and sufficient to confer immunity to CDI, thereby preventing cells ex...

The asymmetric unit of the title compound, [Cd2(C7H4NO4)4(C6H4N2)4], contains one CdII atom, two 3-nitro-benzoate (NB) anions and two 3-cyano-pyridine (CPy) ligands. The two CPy ligands act as monodentate N(pyridine)-bonding ligands, while the two NB anions act as bidentate ligands through the carboxyl-ate O atoms. The centrosymmetric dinuclear complex is generated by application of inversion s...
