The PilT retraction ATPase promotes both extension and retraction of the MSHA type IVa pilus in Vibrio cholerae

H. Q. Hughes, N. D. Christman, T. N. Dalia, C. K. Ellison, A. B. Dalia

This study shows that PilT promotes both extension and retraction of MSHA type IVa pili in Vibrio cholerae, challenging the conventional understanding of T4aP dynamics.

Type IV competence pili in Streptococcus pneumoniae are highly dynamic structures that retract to promote DNA uptake

T. Lam, C. K. Ellison, A. B. Dalia, D. A. Morrison

This study shows that type IV competence pili in Streptococcus pneumoniae dynamically extend and retract, with retraction essential for DNA uptake during natural transformation.

Pseudomonas aeruginosa detachment from surfaces via a self-made small molecule

R. J. Scheffler, Y. Sugimoto, B. P. Bratton, C. K. Ellison, M. D. Koch, M. S. Donia, Z. Gitai

This study identifies a Pseudomonas aeruginosa-produced small molecule, MHQ, that disperses surface-attached bacteria by inhibiting Type IV Pili activity.

Acinetobacter baylyi regulates type IV pilus synthesis by employing two extension motors and a motor protein inhibitor

C. K. Ellison, T. N. Dalia, C. A. Klancher, J. W. Shaevitz, Z. Gitai, A. B. Dalia

This study identifies two extension motors and an inhibitor for type IV pilus synthesis in Acinetobacter baylyi, challenging the previous belief that only one motor is involved.

Surface Sensing Stimulates Cellular Differentiation in Caulobacter crescentus

R. A. Snyder, C. K. Ellison, G. B. Severin, C. M. Waters, Y. V. Brun

This study shows that surface contact and mechanosensing via pilus activity changes stimulate cellular differentiation and cell cycle progression in Caulobacter crescentus.

A bifunctional ATPase drives tad pilus extension and retraction

C. K. Ellison, J. Kan, J. L. Chlebek, K. R. Hummels, G. Panis, P. H. Viollier, N. Biais, A. B. Dalia, Y. Brun

This study identifies a bifunctional ATPase, CpaF, that drives both extension and retraction of tad pili in Caulobacter crescentus through ATP hydrolysis.

Obstruction of pilus retraction stimulates bacterial surface sensing

C. K. Ellison, J. Kan, R. S. Dillard, D. T. Kysela, C. M. Hampton, Z. Ke, E. R. Wright, N. Biais, A. B. Dalia, Y. V. Brun

The paper shows that blocking pilus retraction in Caulobacter crescentus stimulates holdfast synthesis without surface contact, indicating pilus retraction is used for surface sensing.
