Finding needles in haystacks: identification of novel conserved PETase enzymes in Streptomyces

J.-A. Verschoor, M. Croese, S. Lakemeier, A. Mugge, C. Burgers, P. Innocenti, J. Willemse, M. Crooijmans, G. van Wezel, A. Ram, J. de Winde

The paper identifies and analyzes three variants of lipase A from Streptomyces that show PET-degrading activity, with S2LipA demonstrating efficient degradation of BHET and PET films.

The plant stress hormone jasmonic acid evokes defensive responses in streptomycetes

A. van der Meij, S. S. Elsayed, C. Du, J. Willemse, T. M. Wood, N. I. Martin, J. M. Raaijmakers, G. van Wezel

This paper shows that plant hormones jasmonic acid and methyljasmonate alter growth, development, and antibiotic production in Streptomyces, with amino acid conjugation inactivating the hormone as a bacterial defense mechanism.

Branching of sporogenic aerial hyphae in sflA and sflB mutants of Streptomyces coelicolor correlates to ectopic localization of DivIVA and FtsZ in time and space

L. Zhang, J. Willemse, P. Yague, E. de Waal, D. Claessen, G. P. van Wezel

This study shows that SflA and SflB mutants of Streptomyces coelicolor exhibit hyphal branching and ectopic DivIVA/FtsZ localization during sporulation.

A novel and conserved cell wall enzyme that can substitute for the Lipid II synthase MurG

L. Zhang, K. Ramijan, V. Carrion, L. van der Aart, J. Willemse, G. Van Wezel, D. Claessen

The paper identifies a novel enzyme, MurG2, that can substitute for the essential MurG enzyme in Lipid II synthesis across different bacterial genera.

Control of septum thickness by a large protein ring

M. Wenzel, I. Celik Gulsoy, Y. Gao, J. Willemse, M. G. M. van Rosmalen, G. wuite, W. Roos, L. W. Hamoen

This study shows that SepF protein rings in bacteria control septal thickness, with ring diameter correlating to septum thickness and manipulation of ring size altering septum thickness.

Stress-induced formation of cell wall-deficient cells in filamentous actinomycetes

K. Ramijan, E. Ultee, J. Willemse, J. Wondergem, D. Heinrich, A. Briegel, G. van Wezel, D. Claessen

This study shows filamentous actinomycetes can naturally form cell wall-deficient S-cells under hyperosmotic stress, which can transition to stable wall-less forms with prolonged exposure.

Sporulation-specific cell division defects in ylmE mutants of Streptomyces coelicolor are rescued by additional deletion of ylmD

L. Zhang, J. Willemse, P. A. Hoskisson, G. van Wezel

This study shows that deletion of ylmE in Streptomyces coelicolor causes severe sporulation defects, which are rescued by also deleting ylmD.
