Abstract
In the present paper we report the biochemical characteristics of the recombinant tick (Boophilus microplus) gut antigen Bm86 that previousl y has been cloned, expressed and recovered at high levels in the methy lotrophic yeast Pichia pastoris. The results demonstrate that rBm86 ha d a modification at position 92 (Thr replaced by Ile) and aggregated, forming particles ranging between 17 and 40 nm. The rBm86 was N-glycos ylated, having at least two non-glycosylated sequons (Asn-329 and Asn- 363) and a ratio of only 0.4/65 (free Cys/total Cys)/mol of protein.
