- A Bacteroidetes locus dedicated to fungal 1,6-β-glucan degradation: Unique substrate conformation drives specificity of the key endo-1,6-β-glucanase
Temple, The Journal of biological chemistry 2017 - “...locus PUL 1,6--glucan ( 10 , 12 ). PUL 1,6--glucan was predicted to extend from bt3309 to bt3314 ( Fig. 1 A ) and is predicted to encode five proteins: a SusR type regulator (BT3309), a SusCD-like pair (BT331011), and enzymes belonging to GH30_3 (BT3312) and...”
- “...five genes in this locus were evaluated by RT-PCR. The gene encoding the PUL regulator BT3309 was not activated by pustulan; bt3314 was up-regulated 10-fold; and transcription of the other genes in the locus increased 100-fold. The PUL was not activated when B. thetaiotaomicron was cultured...”
