Abstract Single stranded DNA (ssDNA) binding proteins (SSBs) bind selectively to ssDNA with high affinity and little sequence specificity, preventing ssDNA from annealing to its complementary sequence. Previously, Ha Lab showed E. coli SSB, a representative homotetrameric SSB, moving on... Read More

Abstract The structure analysis of large biomolecules such as proteins and peptides by mass spectrometry (MS) is very challenging. However, recently introduced MS techniques facilitate this process by controlled fragmentation. Often physiological modifications take place at the amino acid side... Read More

Abstract.  Despite decades of research regarding best practices for the teaching and learning chemistry, as well as two sets of national reform documents for science education, classroom instruction in high school chemistry classroom remains mostly unchanged. One key reason for... Read More
