Jd. Gabe et al., IDENTIFICATION OF A LINKED SET OF GENES IN SERPULINA-HYODYSENTERIAE (B204) PREDICTED TO ENCODE CLOSELY-RELATED 39-KILODALTON EXTRACYTOPLASMIC PROTEINS, Journal of bacteriology, 180(2), 1998, pp. 444-448
A tandem pair of nearly identical genes from Serpulina hyodysenteriae
(B204) were cloned and sequenced. The full open reading frame of one g
ene and the partial open reading frame of the neighboring gene appear
to encode secreted proteins which are homologous to, yet distinct from
, the 39-kDa extracytoplasmic protein purified from the membrane fract
ion of S. hyodysenteriae. We have designated these newly identified ge
nes vspA and vspB (for variable surface protein).
