Roy R, Balaram P
J Pept Res
. 2004 Mar;
63(3):279-89.
PMID: 15049840
This review briefly surveys the conformational properties of guest omega-amino acid residues when incorporated into host alpha-peptide sequences. The results presented focus primarily on the use of beta- and gamma-residues...

PMID: 10574779
Background: The Escherichia coli peptide antibiotic microcin B17 (MccB17) contains thiazole and oxazole heterocycles derived from a distributive yet directional cyclization of cysteines and serines in the McbA precursor catalyzed...

Biochemistry
. 1999 Apr;
38(15):4768-81.
PMID: 10200165
In the maturation of the Escherichia coli antibiotic Microcin B17 (MccB17), the McbA prepro-antibiotic is modified post-translationally by the multimeric microcin synthetase complex (composed of the McbB, -C, and -D...

J Vet Diagn Invest
. 1999 Mar;
11(2):162-9.
PMID: 10098689
A genomic library of Mycoplasma synoviae (MS) was generated by using bacteriophage lambda gt11 as a cloning and expression vector. Identification of recombinant clones highly specific to MS was achieved...

Chem Biol
. 1998 Jul;
5(7):373-84.
PMID: 9662507
Background: The Escherichia coli peptide antibiotic microcin B17 (MccB17) contains four oxazole and four thiazole rings introduced post-translationally in the 69 amino acid McbA gene product, an MccB17 precursor, by...

. 1998 May;
5(4):217-28.
PMID: 9545435
Background: The peptide antibiotic microcin B17 (MccB17) contains oxazole and thiazole heterocycles formed by the post-translational modification of four cysteine and four serine residues. An amino-terminal propeptide targets the 69...

. 1997 Jun;
10(6):691-8.
PMID: 9278283
The transaminase activity of two new semisynthetic RNase-S proteins incorporating a pyridoxamine moiety at the active site has been evaluated. A chemically competent derivative of pyridoxamine phosphate was incorporated into...
