Extension of the substrate spectrum by an amino acid substitution at residue 219 in the Citrobacter freundii cephalosporinase.

Tsukamoto, K, Ohno, R, Sawai, T

The cephalosporinase of Citrobacter freundii GN346 is a class C beta-lactamase, consisting of 361 amino acids and exhibiting the substrate profile of a typical cephalosporinase. On the conversion of...

Characterization of the immunoglobulin heavy chain complementarity determining region (CDR)-III sequences from human B cell precursor acute lymphoblastic leukemia cells.

Kiyoi, H, Naoe, T, Horibe, K, Ohno, R

Sequence analysis of the immunoglobulin heavy chain complementarity determining region (CDR)-III of B-lineage cells at various stages has provided important insights concerning B cell maturation and...

Comparable profiles of the immunoglobulin heavy chain complementarity determining region (CDR)-3 in CD5+ and CD5- human cord blood B lymphocytes.

Kiyoi, H, Naito, K, Ohno, R, Naoe, T

It has been suggested that CD5+ B cells are closely related to the pathogenesis of autoimmune disease or chronic lymphocytic leukaemia, whereas the origin and physiological role of CD5+ B cells...

Comparison of the immunoglobulin heavy-chain complementarity determining region-3 structure among the DNA sequences and the mu- and gamma-transcripts in human B-lineage cells.

Kiyoi, H, Mori, H, Horibe, K, Ohno, R, Naoe, T

To study the recombinational significance of the (immunoglobulin heavy) IgH chain gene in human B-cell development, we compared the complementarity determining region (CDR)-3 sequences of the DNA and...

L-asparaginase: suppression of the immune response of mice to sheep red blood cells

Ohno, R., Harris, J. E., Hersh, E. M.

L-asparaginase was immunosuppressive in mice. A single injection of 1000 I.U. of L-asparaginase markedly suppressed the direct haemolytic plaque forming cell response to immunization with sheep red...
