Abstract

When Lactobacillus buchneri was grown in the presence of [hydroxyl-18O]serine and pyridoxamine, no 18O was found in its histidine decarboxylase (HisDCase). However, when pyridoxamine was omitted from the growth medium, the labeled serine was incorporated into the HisDCase without dilution. Internal serine residues of the enzyme contained 18O only in their hydroxyl group, while the COOH-terminal serine of the beta chain of HisDCase contained equal amounts of 18O in both its hydroxyl and carboxyl group. This enzyme, like the HisDCase from Lactobacillus 30a (Recsei, P. A., Huynh, Q. K., and Snell, E. E. (1983) Proc. Natl. Acad. Sci. U.S.A. 80, 973-977), therefore, arises by nonhydrolytic serinolysis of its proenzyme. This result, together with comparative sequence data (Huynh, Q. K., and Snell, E. E. (1985) J. Biol. Chem. 260, 2798-2803), makes it highly probable that all of the pyruvoyl-dependent HisDCases arise by a similar mechanism from inactive proenzymes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
