Genome-wide analysis of the rice and arabidopsis () gene families and identification of wheat genes by EST data mining-4

E 49 arabidopsis nsLTPs and the 156 wheat nsLTPs presented in Table 1, Table 2, and Additional file , respectively. AtLTPII.8 that appears to be more distantly related to other type II sequences (see the phylogenetic analysis) was excluded. The values allowing direct identification of the nsLTP type are grey boxed. cysteine residue number 6 is missing in AtLTPII.10. cysteine residue number 7 is missing in TaLTPVIa.5. cysteine residue number 8 is missing in AtLTPI.1. AtLTPII.10, OsLTPVI.1, OsLTPVI.2, OsLTPVI.4, and TaLTPVIa subfamily members harbor an extra cysteine residue. All type VI contain a Val 4 aa before Cys7 and a Met 10 aa before Cys7 allowing a distinction between type IV and type VI. AtLTPII.6 harbors an extra cysteine residue. TaLTPIVc.1 and TaLTPIVa subfamily members harbor an extra cysteine residue. 12 amino acid residues were counted for the TaLTPIVd.1 that displays no CXC motif. OsLTPVII.1 and TaLTPVIIa.1 subfamily members harbor an extra cysteine residue.<b>Copyright information:</b>Taken from "Genome-wide analysis of the rice and arabidopsis () gene families and identification of wheat genes by EST data mining"http://www.biomedcentral.com/1471-2164/9/86BMC Genomics 2008;9():86-86.Published online 21 Feb 2008PMCID:PMC2277411.

本数据集涵盖49个拟南芥非特异性脂质转移蛋白（non-specific lipid transfer proteins, nsLTPs）与156个小麦nsLTPs，三者分别列于表1、表2及附加文件中。与其他II型序列亲缘关系较远的AtLTPII.8（详见系统发育分析）已被排除出本数据集。可直接用于鉴定nsLTP类型的相关数值已以灰色框标注。

AtLTPII.10缺失第6号半胱氨酸残基，TaLTPVIa.5缺失第7号半胱氨酸残基，AtLTPI.1缺失第8号半胱氨酸残基。AtLTPII.10、OsLTPVI.1、OsLTPVI.2、OsLTPVI.4及TaLTPVIa亚家族成员均额外携带一个半胱氨酸残基。所有VI型nsLTP均在第7号半胱氨酸残基上游4个氨基酸位点处存在缬氨酸（Val），且在第7号半胱氨酸残基上游10个氨基酸位点处存在甲硫氨酸（Met），借此可实现IV型与VI型nsLTP的区分。AtLTPII.6额外携带一个半胱氨酸残基。TaLTPIVc.1与TaLTPIVa亚家族成员均额外携带一个半胱氨酸残基。TaLTPIVd.1未呈现CXC基序，其氨基酸残基计数为12。OsLTPVII.1与TaLTPVIIa.1亚家族成员均额外携带一个半胱氨酸残基。
