Structure of MltG from Mycobacterium abscessus reveals structural plasticity between composed domains

We provide the structure of MltG of the lytic transglycosyl­ase family in this study. We show that MltG has a flexible peptidoglycan-binding domain and exists as a monomer in solution. Further, the putative active site of Mycobacterium abscessus MltG has been revealed using structural analysis and sequence comparison. This research significantly advances our comprehension of the transglycosyl­ation process mediated by the MltG family, providing valuable insights that can inform the development of next-generation antibiotics to specifically target M. abscessus.

Tuning structural modulation and magnetic properties in metal–organic coordination polymers [CH₃NH₃]Co_xNi_1−x(HCOO)₃

We show that the modulated phase transitions in solid solutions of [CH₃NH₃]Co_xNi_1−x(HCOO)₃, with x = 0.25 (1), x = 0.50 (2) and x = 0.75 (3), can be tuned by the metal ratio, which offers the opportunity to consciously build molecular compounds with adjustable properties by doping metal sites.
