  1. aGH: glycosyl hydrolase; RPKM: Reads Per Kilobase of exon model per million mapped reads. bRPKM is a method for estimating relative expression levels of a transcriptome by normalizing short-read expressed tags from deep sequencing over ORF length and total reads (RPKM) [35]. cOnline protein sequences hits by using only ESI-Trap LC-MS/MS data against MASCOT online database.
