Figure 1From: Expression of an extremely acidic β-1,4-glucanase from thermoacidophilic Alicyclobacillus sp. A4 in Pichia pastoris is improved by truncating the gene sequenceNucleotide and amino acid sequences of the β-1,4-glucanase, CelA4, from the thermoacidophilic Alicyclobacillus sp. A4. The residues of the putative signal peptide (residues 1-39) are underlined, those of the linker region are underlined twice, and the threonine-rich region is indicated by dashed line, nine putative N-glycosylation sites are indicated by black boxes.Back to article page
