Novel Anti-Fungal <span style="font-variant: small-caps">d</span>-Laminaripentaose-Releasing Endo-β-1,3-glucanase with a RICIN-like Domain from <i>Cellulosimicrobium funkei</i> HY-... by Lu Bai, Jonghoon Kim, Kwang-Hee Son, Dong-Ha Shin, Bon-Hwan Ku, Do Young Kim, Ho-Yong Park

“…The recombinant enzyme (rGluY: 57.5 kDa) displayed the highest degradation activity for laminarin at pH 4.5 and 40 °C, while the polysaccharide was maximally decomposed by its C-terminal truncated mutant enzyme (rGluYΔRICIN: 42.0 kDa) at pH 5.5 and 45 °C. The specific activity (26.0 U/mg) of rGluY for laminarin was 2.6-fold higher than that (9.8 U/mg) of rGluYΔRICIN for the same polysaccharide. …”

Identification and Characterization of a Novel, Cold-Adapted <span style="font-variant: small-caps">d</span>-Xylobiose- and <span style="font-variant: small-caps">d</span>-Xylose-R... by Do Young Kim, Jonghoon Kim, Yung Mi Lee, Jong Suk Lee, Dong-Ha Shin, Bon-Hwan Ku, Kwang-Hee Son, Ho-Yong Park

“…The recombinant enzyme (rXylR: 42.0 kDa) showed the highest beechwood xylan-degrading activity at pH 5.5 and 40 °C, and displayed 12% of its maximum activity even at 4 °C. rXylR was not only almost completely inhibited by 5 mM <i>N</i>-bromosuccinimide or metal ions (each 1 mM) including Hg²⁺, Ca²⁺, or Cu²⁺ but also significantly suppressed by 1 mM Ni²⁺, Zn²⁺, or Fe²⁺. …”
