We present the first comprehensive analysis of a diploid human genome that combines single-molecule sequencing with single-molecule genome maps. Our hybrid assembly markedly improves upon the contiguity observed from traditional shotgun sequencing approaches, with scaffold N50 values approaching 30 Mb, and we identified complex structural variants (SVs)(More)
Pre-steady-state kinetic studies on Y-family DNA polymerase η (Polη) have suggested that the polymerase undergoes a rate-limiting conformational change step before the phosphoryl transfer of the incoming nucleotide to the primer terminus. However, the nature of this rate-limiting conformational change step has been unclear, due in part to the lack of(More)
MOTIVATION Resolving tandemly repeated genomic sequences is a necessary step in improving our understanding of the human genome. Short tandem repeats (TRs), or microsatellites, are often used as molecular markers in genetics, and clinically, variation in microsatellites can lead to genetic disorders like Huntington's diseases. Accurately resolving repeats,(More)
A major clinical problem in the use of cisplatin to treat cancers is tumor resistance. DNA polymerase η (Pol-η) is a crucial polymerase that allows cancer cells to cope with the cisplatin-DNA adducts that are formed during chemotherapy. We present here a structure of human Pol-η inserting deoxycytidine triphosphate (dCTP) opposite a cisplatin intrastrand(More)
Restriction enzymes share little or no sequence homology with the exception of isoschizomers, or enzymes that recognize and cleave the same DNA sequence. We present here the structure of a BamHI isoschizomer, OkrAI, bound to the same DNA sequence (TATGGATCCATA) as that cocrystallized with BamHI. We show that OkrAI is a more minimal version of BamHI, lacking(More)
Studies directed at developing a broadly acting non-nucleoside inhibitor of HCV NS5B led to the discovery of a novel structural class of 5-aryl benzofurans that simultaneously interact with both the palm I and palm II binding regions. An initial candidate was potent in vitro against HCV GT1a and GT1b replicons, and induced multi-log reductions in HCV viral(More)
This paper describes novel concepts of space bionanorobotic systems that are based on revolutionary bio-nano-mechanisms formed by protein and DNA based nano-components. Nano-robots are controllable machines at the nano (10) meter or molecular scale that are composed of nano-scale components. With the modern scientific capabilities, it has become possible to(More)
