The first step in contemporary protein synthesis is the activation of amino acids by aminoacyl-tRNA synthetases, which form aminoacyl adenylates from ATP and amino acids. Previously, an RNA called KK13 was shown to catalyze amino acid activation by forming a bond between an amino acid and the α-phosphate of the 5'-triphosphate of its own RNA, analogous to the bond formed in aminoacyl adenylates. In the present study, we describe a putative novel RNA with catalytic activity, identified among previously uncharacterized sequences. The RNA, KK33-1 (114 nucleotides), exhibited activity comparable to that of a previously characterized ribozyme, KK13, as judged by a malachite green assay detecting pyrophosphate released from the 5'-triphosphate of the RNA. Guided by predicted secondary structure, truncation experiments indicated that certain smaller variants of KK33-1 can retain amino acid activation activity. Although attention was drawn to a CAAC sequence common to KK13 and KK33-1, which was positioned near the putative reaction site according to tertiary structure prediction, a mutational analysis revealed that this motif is not essential for catalysis. Together, the behaviors of KK33-1 and its mutants provide insights into the structural features supporting amino acid activation, refining our understanding of the ribozyme's functional architecture.

A formal operational model of quantum autopoiesis is presented that is physically grounded in photon-fermion interactions and in the phase structure of the electromagnetic field. The continuous electromagnetic phase, associated with a U(1) reference symmetry, is treated as an underlying substrate that, under local interaction conditions and finite resolution, yields a finite set of stable phase classes Zn, interpreted operationally as a symbolic alphabet. Identity persistence is defined by sustained coherence between the electromagnetic field and existing fermionic structure. When coherence is sufficient, the current symbolic state is carried forward; when coherence is locally reduced and admissible transitions exist, discrete phase updates occur. Photon-fermion interactions are thus treated as physically admissible gates acting on elements of Zn. Formally, persistence is captured by the recursive identity operator I=λs.s, while gate application corresponds to controlled symbolic update I=λs.δs. Within this framework, three questions are addressed. First, identity persistence is characterized as the ability to carry symbols across time under coherence. Second, new knowledge discovery is defined as the successful stabilization of a discrete update in fermionic (symbolic) structure. Third, the accumulation of symbolic logic structure arises from alternating phases of persistence and targeted updates, producing reusable structure without loss of identity. The significance of the model lies in its integration of identity, knowledge discovery, and symbolic computation within a single physically grounded formalism, where computation emerges operationally from composable transitions under physical constraints.
