“…In previous studies, only the interaction between the outer membrane protein Caf1A of Y. pestis and IL-1β has been investigated in detail [25]. The binding affinity of that interaction was high, with a K d of 140 ± 14 pM.…”

“…Cultures carrying the appropriate plasmid, as indicated, were routinely grown at 37 mC in LB broth containing ampicillin (100 µg\ml) and kanamycin (40 µg\ml) as required. The cosmid pFS2 (carrying the entire f1 operon) [4] and plasmids p12R (carrying a major fragment of the f1 operon) [3], pTCA1 (encoding Caf1M under ptrc control) [14] and pFM1 (encoding Caf1M and the Caf1 subunit under ptrc control) [14] have been described. For overexpression of Caf1 subunit alone, a 596 bp BamHI fragment encompassing the majority of the caf1M gene (from nucleotide 242 to the end) was deleted from pFM1 to yield pFM1S (encoding only the Caf1 subunit under ptrc control).…”

“…Caf1M was isolated from induced E. coli DH5α\pTCA1 cells by osmotic shock and purified to homogeneity using MonoQ and Superose 12 H\R chromotography as previously described [14].…”

“…За-вьялов с соавт. [97] сделали предположение, что F1 может вступать в конкуренцию с интерлей-кинами 1a, 1b и 1ra за связывание с рецепторами на лимфоидных клетках, препятствуя развитию адекватного иммунного ответа. В свою очередь молекулярный ашер Caf1A может сорбировать интерлейкины, препятствуя их контакту с мак-рофагами.…”
