Characterization of the type strain ofBacillus thuringiensissubsp.camerounserotype H32 [PDF]

open access: yesFEMS Microbiology Letters, 1994
The strain 273 B, the type strain of a H serotype of Bacillus thuringiensis not yet characterized: B. thuringiensis subsp. cameroun, serotype H32, was isolated from soil samples collected in Cameroon. This strain produces cuboidal parasporal bodies composed of two major proteins of 53 kDa and 35 kDa.

Modeling the Histogenetic Switch Between Enameloid and Enamel. [PDF]

open access: yesEvol Dev
This evo–devo exploration of ~550,000 histogenetic simulations forming dentine, enameloid, and enamel identifies 38 independent ways to induce the enameloid–enamel transition, with delayed matrix vesicle secretion (SVO‐) emerging as the key modification, providing new insights into the origin of enamel in early osteichthyans.

Replacing Arginine 33 for Alanine in the Hemophore HasA from Pseudomonas aeruginosa Causes Closure of the H32 Loop in the Apo-Protein [PDF]

open access: yes, 2016
Previous characterization of hemophores from Serratia marcescens (HasAs), Pseudomonas aeruginosa (HasAp), and Yersinia pestis (HasAyp) showed that hemin binds between two loops, where it is axially coordinated by H32 and Y75. The Y75 loop is structurally
