Bioinformatic Aanlysis of IDD Gene Family in Phyllostachys heterocycla
2014
IDD gene family encode hybrid transcription factor. In this study, nine IDD genes in Phyllostachys heterocycla,named PhIDD1 and PhIDD1-8 were obtained by local blast. They all contain IDD-domain which is a putative nuclear location signal and four zinc finger motifs. All nine putative proteins were hydrophilic,and their isoelectric point distributed between 8. 8 and 9. 7 except for PhIDD2( 5. 6). Ala,Ser and Gly were abundant in these proteins. Constructions of α-helixs and random coils in these proteins were dominant elements,β-turns and extended strains interspersing over the whole proteins. The prediction of these proteins showed that the number of phosphorylation sites were from 20 to 29,α-helixs,β-turns and random coils of PhIDD1 were formed at 63-175amino acid and there is a zinc binding site at this space.
