A-54556A is a natural acyldepsipeptide (ADEP) antibiotic isolated from the fermentation broth of S. hawaiiensis.{24688} Like other ADEP antibiotics, A-54556A binds to the ATP-dependent Clp protease proteolytic subunit ClpP, resulting in constitutive activation of this bacterial protease.{27768,27766,27765} This leads to uncontrolled proteolysis, inhibition of bacterial cell division, and, ultimately, cell death.{24688,27767} A-54556A preferentially targets Gram-positive bacteria, including staphylococci, streptococci, and enterococci, with minimum inhibitory concentration values in the submicrogram/milliliter range.{27767} ADEP antibiotics are effective against chronic infections as they are able to eradicate chronic biofilm infections, particularly when combined with rifampicin.{24689}

    The PtdIn phosphates play an important role in the generation and transduction of intracellular signals.{8344,4096,14518} PtdIns-(3,4,5)-P3-biotin is an affinity probe which allows the PIP3 to be detected through an interaction with the biotin ligand. This design allows PtdIns-(3,4,5)-P3-biotin to serve as a general probe for any protein with a high affinity binding interaction with inositol-(3,4,5)-triphosphate phospholipids, such as phosphatidylinositol 3-kinase, PTEN, or PH-domain-containing proteins.
