The Cupin Protein, Dehydratase Pac13 is a Homodimer [PDF]

open access: yes, 2019
ABSTRACTCupin proteins share a double-stranded β-helix fold, form one of the largest superfamilies and possess remarkable functional diversity. They usually form homooligomeric states. Michailidou et al. recently reported that a cupin protein Pac13, which is a dehydratase mediating the formation of the 3’-deoxy nucleoside of pacidamycins, is an unusual,

A low oxygen threshold for physiological responses and trace metal quotas of Prochlorococcus and Synechococcus

open access: yesLimnology and Oceanography, Volume 70, Issue 9, Page 2569-2581, September 2025.
Abstract Continued human activity is expected to accelerate ocean deoxygenation, leading to the expansion and shallowing of oxygen‐deficient zones (ODZs). This decline in oxygen may impact both phytoplankton growth and trace metal uptake. We conducted culture experiments with Prochlorococcus MIT9313 and Synechococcus XM‐24, two numerically dominant ...

Making moral selves through comparison: Narratives of moral decline and the modern virtuous self among middle‐class older adults in Nepal

open access: yesEthos, Volume 53, Issue 3, September 2025.
Abstract During fieldwork among older adults in middle‐class families in the city of Bhaktapur (2018–2019), I recurrently came across comparative narratives of moral decline, depicting a stark contrast between the present time and a mythical past where ageing parents were treated “as gods.” In this paper, I analyze how, through acts of comparisons ...
