1 Roles of disulfide bonds in recombinant human interleukin 6 conformation. Disulfides interleukin 6 Homo sapiens
2 Human IL-6 has two disulfide bonds linking Cys45 to Cys51 and Cys74 to Cys84, respectively. Disulfides interleukin 6 Homo sapiens
3 To address the structural importance of these disulfide bonds in the formation and stabilization of IL-6 secondary and tertiary structures, we have generated a panel of disulfide bond-deficient rIL-6 analogs both by chemical reduction and alkylation as well as by site-directed mutagenesis. Disulfides interleukin 6 Homo sapiens
4 Our results suggest that the second disulfide bridge plays a critical role in maintaining the spatial relationship between the putative IL-6 A and D helices. Disulfides interleukin 6 Homo sapiens
