Abstract
The complete nucleotide sequence of endAFS, an endoglucanase gene isolated from the ruminal anaerobe Fibrobacter succinogenes AR1, was determined. endAFS encodes two overlapping open reading frames (ORF1 and ORF2), and it was proposed that a -1 ribosomal frameshift was required to allow contiguous synthesis of a 453-amino-acid endoglucanase. A proline- and threonine-rich region at the C terminus of ORF1 and rare codons for arginine and threonine were coincident with the proposed frameshift site. ENDAFS is proposed to be a member of subgroup 1 of family E endoglucanases, of which endoglucanases from Thermomonospora fusca and Persea americana (avocado) are also members. Endoglucanases from Clostridium thermocellum and Pseudomonas fluorescens form subgroup 2.
