1H, 15N and 13C resonance assignments of a repetitive domain of tubuliform spidroin 2
Spider silk is renowned for its excellent mechanical properties. Among six types of silk and one silk glue produced by different abdominal glands for various purposes, tubuliform (eggcase) silk is unique due to its high serine and low glycine content. Eggcase silk is spun from at least two spidroins, tubuliform spidroin 1 (TuSp1) and TuSp2. TuSp1 and TuSp2 were identified as the major and the minor components in tubuliform glands, respectively. TuSp2 consists of multiple repetitive (RP) domains with short terminal tails and shares very limited homology to all known spidroins. Here we report backbone and side chain resonance assignments of TuSp2-RP as a basis for structural and functional studies on eggcase silk formation.
期刊介绍：
Biomolecular NMR Assignments provides a forum for publishing sequence-specific resonance assignments for proteins and nucleic acids as Assignment Notes. Chemical shifts for NMR-active nuclei in macromolecules contain detailed information on molecular conformation and properties.
Publication of resonance assignments in Biomolecular NMR Assignments ensures that these data are deposited into a public database at BioMagResBank (BMRB; http://www.bmrb.wisc.edu/), where they are available to other researchers. Coverage includes proteins and nucleic acids; Assignment Notes are processed for rapid online publication and are published in biannual online editions in June and December.
