Thermoanaerobacter tengcongensis is a rod-shaped, Gram-negative, anaerobic eubacterium that was isolated from a fresh water hot spring in Tengchong, China. Using a"whole-genome-shotgun"method, we sequenced its 2, 689, 445-bp genome from an isolate, MB4〓(Genbank Accession Number AE008691). The genome encodes 2, 588 predicted coding sequences . Among them, 1, 764 (68. 2％) are classified according to homology to other documented proteins, and the rest, 824 CDS (31. 8％), are functionally unknown. One of the interesting features of the T. tengcongensis genome is that 86. 7％ of its genes are encoded on the leading strand of DNA replication.
