The lipocalin superfamily of proteins functions in the binding and transport of a variety of important hydrophobic molecules. Tear lipocalin is a promiscuous lipid binding member of the family and serves as a paradigm to study the molecular determina

Large conductance voltage and Ca 2+ -dependent K + channels (BK Ca ) are activated by both membrane depolarization and intracellular Ca 2+ . Recent studies on bacterial channels have proposed that a Ca 2+ -induced conformational change within special

Carbon monoxide (CO) is a recognized gasotransmitter that regulates BK channel activity, causing vasodilatory effects. It is thought that CO interacts with the intracellular portion of BK channels, which consists of the assembly of structural domains

Tear lipocalin (TL), a major component of human tears, shows pH-dependent endogenous ligand binding. The structural and conformational changes associated with ligand release in the pH range of 7.5-3.0 are monitored by circular dichroism spectroscopy

Previous studies suggest that the conserved Trp17 on strand A of TL has a role in lipocalin stability and interacts, directly or indirectly, with Ile98 and Phe99 on strand G to influence ligand binding. Here, we determined the proximity of Trp17 to I

The solution structure of human TL was deduced from the position of the emission peaks after site-directed tryptophan fluorescence (SDTF). The fluorescent amino acid tryptophan was sequentially substituted for each native amino acid in the sequence.

Several lipocalins contain conserved amino acid sequences similar to the phosphodiester bond cleavage domain of sugar non-specific magnesium-dependent nucleases of the Serratia marcescens type. His-89 and Glu-127 of the S. marcescens endonuclease are

The principal lipid binding protein in tears, tear lipocalin (TL), binds acid and the fluorescent fatty acid analogs, DAUDA and 16-AP at one site TL compete for this binding site. A fluorescent competitive binding assay revealed that apo-TL has a hig
