Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

On union of regular near-rings
‘A semigroup is completely regular if and only if it is a union of groups’ — an analogue of this structure theorem has been obtained in the setting of seminearrings [see cf. R. Mukherjee, T. Manna and P. Pal, A note on additively completely regular seminearrings, Semigroup Forum 100(1) (2020) 339–347].

Structural and biochemical analysis of a B12 superbinder
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

On the Structure of Near-Rings via P-Semiderivations
This paper introduces the concept of a P-semiderivation on a near-ring N, which serves as a generalization of the classical notion of a semiderivation.

Prime near-ring modules and their links with the generalised group near-ring [PDF]
In view of the facts that the definition of a ring led to the definition of a near- ring, the definition of a ring module led to the definition of a near-ring module, prime rings resulted in investigations with respect to primeness in near-rings, one is ...

Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

COMMUTATIVITY AND DECOMPOSITION FOR NEAR RINGS
Let $R$ be a distributively generated (d.g) near ring satisfy one of the following condit ions. (*) For each $x$, $y$ in $R$, there exists a positive integer $n =n(x,y)$ such that $xy =(yx)^n$.(**) For each $x$, $y$ in $R$, there exist positive integers $m = m(x,y)$ and $n = n(x,y)$ for which $xy = y^m x^n$.

Fundamental properties of near-rings [PDF]
The basic properties of near-rings are examined, and are then used to develop several fundamental theorems, among which are the Factor Theorem, the Isomorphism Theorems, the Correspondence Theorem, and theorems concerning near-ring embeddings.
