  • The catalytic importance of the A76 2'-OH group in aminoacylation mirrors a similar role for this moiety that has recently been demonstrated during peptidyl transfer on the ribosome.

  • Two proteases capable of decreasing dough strength when added to wheat flour were purified from Maitake and these were both thought to be peptidyl-Lys metalloendopeptidase.

  • Beta lactamases have kept these activities, despite structural changes which have resulted in losing DD-peptidyl ligase activity, if these activities are kept, then the enzyme is more robust than Axe contends but to be fair this is harder to monitor in the kinds of experiments Axe did.. gutbag

    Axe (2004) and the evolution of enzyme function - The Panda's Thumb

  • Speaking of undersampling, it would have been good to look at the breakdown of common substrates of DD-peptidyl ligases and beta lactamases, such as m-[[phenylacetyl-glycyl]oxy]benzoic acid and see what the muations did to these activities.

  • The proband's collagen had normal collagen folding and normal prolyl 3-hydroxylation, suggesting that CyPB is not the exclusive peptidyl-prolyl cis-trans isomerase that catalyzes the rate-limiting step in collagen

  • They had a homozygous start-codon mutation in the peptidyl-prolyl isomerase B gene (PPIB), which results in a lack of cyclophilin

  • Briefly, peptidyl-prolyl cis-trans isomerase A (PPIA) and heat shock protein 27 kda (HSPB1) increase the expression of superoxide dismutase-1 (SOD1), which regulates catalase (CAT).

  • The translocase eEF2 pushes the peptidyl-tRNA into the P-site and the deacylated tRNA into the E-site, freeing the A-site for another round of elongation.
