The FEBS Journal, EarlyView.Two enzymes from the Thermus thermophilus lysine biosynthetic pathway, LysZ and LysY, unexpectedly exhibit substrate promiscuity. They are able to recognize the LysW intermediates utilized by the ArgW‐mediated arginine route, even though the bacterium already possesses the canonical arginine biosynthetic pathway.

CarD uses a minor groove wedge mechanism to stabilize the RNA polymerase open promoter complex
eLife, 2015 A key point to regulate gene expression is at transcription initiation, and activators play a major role. CarD, an essential activator in Mycobacterium tuberculosis, is found in many bacteria, including Thermus species, but absent in Escherichia coli. To

Antimatter production in proton-proton and heavy-ion collisions at ultrarelativistic energies
, 2011 One of the striking features of particle production at high beam energies is the near equal abundance of matter and antimatter in the central rapidity region. In this paper we study how this symmetry is reached as the beam energy is increased.

Low‐Head Dam Removal Restores Biofilm Structure but Not Function in a Temperate Stream
International Review of Hydrobiology, Volume 111, Issue 1, June 2026.ABSTRACT Barrier removal is a common stream restoration practice aimed at restoring longitudinal connectivity, yet its effects on biofilm structure and function, through alteration of near‐bed hydrodynamics, remain unclear. Using a space‐for‐time substitution approach, we assessed how the presence and removal of a low‐head dam affect biofilm structure ...

Laccases from lactic acid bacteria show cuprous oxidase activity and capture Cu(II) and Ag(I) ions
Protein Science, Volume 35, Issue 1, January 2026.Abstract Several laccases derived from lactic acid bacteria (LAB) display specific structural features, such as two methionine residues at the entrance of the T1Cu center, and an extended C‐terminal end enriched in methionine and histidine. To investigate their functional roles, we engineered mutant variants of the laccase Pp4816 from Pediococcus ...
