lysine decarboxylase
Product Name Confidence: Class 2
CommentModeling evidence, since PAO1 grows on lysine. Also physiological evidence from Fothergill et al. BLAST of Lysine decarboxylase Burkholderia cenocepacia HI2424 vs. P. aeruginosa PAO1 genome gave E = 0 with PA1818. Orn and Arg functions are also in reconstruction.
Evidence for Translation
Identified using nanoflow high-pressure liquid chromatography (HPLC) in conjunction with microelectrospray ionization on LTQ XL mass spectrometer (PMID:24291602).
Charge (pH 7) -13.13
Kyte-Doolittle Hydrophobicity Value -0.083
Molecular Weight (kDa) 82.8
Isoelectric Point (pI) 6.07
