    摘要:

  • Carbohydrate Microarrays for Assaying Galactosyltransferase Activity
    作者:Sungjin Park、Injae Shin
    DOI:10.1021/ol070250l
    日期:2007.4.1
    Carbohydrate microarrays have been used recently for the rapid analysis of glycan-protein or glycan-cell interactions and for the detection of pathogens. As a demonstration of its significance and versatility, the microarray technology has been applied in this effort to assay glycosyltransferase activities. In addition, carbohydrate microarray based methods have been employed to quantitatively determine binding affinities between lectins and carbohydrates.
  • Phagemid Encoded Small Molecules for High Throughput Screening of Chemical Libraries
    作者:Jun Yin、Fei Liu、Martina Schinke、Christian Daly、Christopher T. Walsh
    DOI:10.1021/ja045127t
    日期:2004.10.1
    A new strategy for monovalently displaying small molecules on phage surfaces was developed and applied to high throughput screening for molecules with high binding affinity to the target protein. Peptidyl carrier protein (PCP) excised from nonribosomal peptide synthetase was monovalently displayed on the surface of M13 phage as pIII fusion proteins. Small molecules of diverse structures were conjugated to coenzyme A (CoA) and then covalently attached to the phage displayed PCP by Sfp phosphopantetheinyl transferase. Because Sfp is broadly promiscuous for the transfer of small molecule linked phosphopantetheinyl moieties to apo PCP domains, this approach will enable displaying libraries of small molecules on phage surfaces. Unique 20-base-pair (bp) DNA sequences were also incorporated into the phagemid DNA so that each compound displayed on the phage surface was encoded by a DNA bar code encapsulated inside the phage coat protein. Single round selection of phage displayed small molecules achieved more than 2000-fold enrichment of small molecules with nM binding affinity to the target protein. The selection process is further accelerated by the use of DNA decoding arrays for identifying the selected small molecules.
