Potent anti-CD5 ricin A chain immunoconjugates from bacterially produced Fab' and F(ab')2.

Better, M, Bernhard, S L, Lei, S P, Fishwild, D M, Lane, J A, Carroll, S F, ...

We have used genetic engineering to obtain secretion of anti-human CD5 antibody fragments from Escherichia coli for conjugation to the 30-kDa form of ricin A chain (RTA30). This was accomplished by...

Modification of the C terminus of cecropin is essential for broad-spectrum antimicrobial activity.

Callaway, J E, Lai, J, Haselbeck, B, Baltaian, M, Bonnesen, S P, Weickmann, J, ...

Cecropin A is a naturally occurring peptide with bactericidal activity against gram-negative and gram-positive bacteria. Production of large quantities of bactericidal peptides that are similar in...

Characterization of the Erwinia carotovora pelB gene and its product pectate lyase.

Lei, S P, Lin, H C, Wang, S S, Callaway, J, Wilcox, G

The pelB gene encodes pectate lyase B, one of three pectate lyases identified in Erwinia carotovora EC. Pectate lyase B was purified from Escherichia coli containing the pelB gene on a recombinant...

araB Gene and nucleotide sequence of the araC gene of Erwinia carotovora.

Lei, S P, Lin, H C, Heffernan, L, Wilcox, G

The araB and araC genes of Erwinia carotovora were expressed in Escherichia coli and Salmonella typhimurium. The araB and araC genes in E. coli, E. carotovora, and S. typhimurium were transcribed in...

Evidence that polygalacturonase is a virulence determinant in Erwinia carotovora.

Lei, S P, Lin, H C, Heffernan, L, Wilcox, G

Polygalacturonase (PG) was purified from Erwinia carotovora EC. A hybrid cosmid, pSH711, that encodes PG activity but not pectate lyase activity was identified from an E. carotovora genomic library...
