Ward N, et al. Among authors: khouri h. PLoS Biol. 2004 Oct;2(10):e303. doi: 10.1371/journal.pbio.0020303. Epub 2004 Sep 21. PLoS Biol. 2004. PMID: 15383840 Free PMC article.
One of the most surprising outcomes of the project is evidence suggesting the existence of previously unsuspected metabolic flexibility in M. capsulatus, including an ability to grow on sugars, oxidize chemolithotrophic hydrogen and sulfur, and live under reduced oxygen te …

Long lag times and high velocities in the motility of natural assemblages of marine bacteria.
Mitchell JG, Pearson L, Bonazinga A, Dillon S, Khouri H, Paxinos R. Mitchell JG, et al. Among authors: khouri h. Appl Environ Microbiol. 1995 Mar;61(3):877-82. doi: 10.1128/aem.61.3.877-882.1995. Appl Environ Microbiol. 1995. PMID: 16534971 Free PMC article.
Cell speeds changed more than an order of magnitude on timescales of milliseconds and hours. The maximum community speed was 144 (mu)m s(sup-1), and the maximum individual burst velocity was 407 (mu)m s(sup-1). In uniform medium, speed was an inverse function of try …

A protein engineering study of the role of aspartate 158 in the catalytic mechanism of papain.
Ménard R, Khouri HE, Plouffe C, Dupras R, Ripoll D, Vernet T, Tessier DC, Lalberté F, Thomas DY, Storer AC. Ménard R, et al. Among authors: khouri he. Biochemistry. 1990 Jul 17;29(28):6706-13. doi: 10.1021/bi00480a021. Biochemistry. 1990. PMID: 2397208
With CBZ-Phe-Arg-MCA as substrate, the kcat/KM and kcat values obtained for the Asp158Asn papain are 20,000 M-1.s-1 and 34 s-1, respectively, as compared with values of 120,000 M-1.s-1 and 51 s-1 obtained for the wild-type papain. ...

Contribution of the glutamine 19 side chain to transition-state stabilization in the oxyanion hole of papain.
Ménard R, Carrière J, Laflamme P, Plouffe C, Khouri HE, Vernet T, Tessier DC, Thomas DY, Storer AC. Ménard R, et al. Among authors: khouri he. Biochemistry. 1991 Sep 17;30(37):8924-8. doi: 10.1021/bi00101a002. Biochemistry. 1991. PMID: 1892809
Mutation of Gln19 to Ala caused a decrease in kcat/KM for hydrolysis of CBZ-Phe-Arg-MCA, which is 7700 M-1 s-1 in the mutant enzyme as compared to 464,000 M-1 s-1 in wild-type papain. With a Gln19Ser variant, the activity is even lower, with a kcat/KM value of 760 …

Removal of an inter-domain hydrogen bond through site-directed mutagenesis: role of serine 176 in the mechanism of papain.
Ménard R, Plouffe C, Khouri HE, Dupras R, Tessier DC, Vernet T, Thomas DY, Storer AC. Ménard R, et al. Among authors: khouri he. Protein Eng. 1991 Feb;4(3):307-11. doi: 10.1093/protein/4.3.307. Protein Eng. 1991. PMID: 1907009
The mutation of Ser176 to an alanine has only a small effect on the kinetic parameters, the kcat/Km for hydrolysis of CBZ-Phe-Arg-MCA by the Ser176Ala enzyme being of 8.1 x 10(4) /M/s compared with 1.2 x 10(5) /M/s for papain. Serine 176 is therefore not essential f …

Importance of hydrogen-bonding interactions involving the side chain of Asp158 in the catalytic mechanism of papain.
Ménard R, Khouri HE, Plouffe C, Laflamme P, Dupras R, Vernet T, Tessier DC, Thomas DY, Storer AC. Ménard R, et al. Among authors: khouri he. Biochemistry. 1991 Jun 4;30(22):5531-8. doi: 10.1021/bi00236a028. Biochemistry. 1991. PMID: 2036422
When CBZ-Phe-Arg-MCA is used as a substrate, the (kcat/KM)obs values at pH 6.5 are 3650 and 494 M-1 s-1 for Asp158Gly and Asp158Ala, respectively, as compared to 119,000 M-1 s-1 for papain. ...
