In the present paper, for a positive integer $r$, we study bi-periodic $r$-Fibonacci sequence and its family of companion sequences, $r$-Lucas type $s$ with $1 \leq s r$, which extend classical Fibonacci Lucas sequences. Afterwards, establish link between Furthermore, give their properties as linear recurrence relations, generating functions, explicit formulas Binet forms.

Aminotransferases (ATs) are pyridoxal 5′-phosphate-dependent enzymes that catalyze the reversible transfer of an amino group from donor to a keto substrate. ATs promising biocatalysts replacing traditional chemical routes for production chiral amines. In this study, in silico-screening metagenomic library isolated Curonian Lagoon identified 11 full-length fold type IV aminotransferases were suc...
