The phrase "a fragment coding for" is correct and usable in written English.
It can be used in contexts related to genetics, molecular biology, or programming, where you are referring to a specific part of a sequence that encodes for a particular function or product.
Example: "The research focused on a fragment coding for a protein involved in cellular signaling."
Alternatives: "a segment encoding for" or "a portion that encodes for".
The NBR1-p62 chimera was generated as follows: a fragment coding for amino acids 1 85 from human NBR1 was cloned into pET-Duet1, followed by insertion of a fragment coding for amino acids 103 443 of p62.
The reporter gene fusion was generated by introducing a fragment coding for an α-helical spacer (troponinC, helix 5, see Figure 3B) between a 5'-luciferase (deleted stop codon) and a 3'-eGFP (deleted start codon) open reading frame (orf).
The TCR transcript first caught our attention because it matched a sequence fragment coding for a T-cell receptor, which is a complex of integral membrane proteins that participates in the activation of T-cells in response to the presentation of an antigen.
A DNA fragment coding for the GST-tag and a TEV-protease site was amplified by PCR from the vector pETM30 (obtained from Gunter Stier, EMBL) and was cloned into the BamHI-restriction site of pQE30N.
A gene fragment coding for AhpC was amplified using the primers peroxi_start_For and peroxi_end_SalI_Rev (Table 1), and the PCR product was fused with a DNA fragment containing a putative promoter region of the NH04 mannitol dehydrogenase gene (mdh) amplified by PCR with the primers thr_prm_XhoI_For and thr_prm_peroxi_Rev.
The size of this PCR product is in good agreement with the figure expected for a DNA fragment coding for the sequenced boophilin fragment (see above).
A cDNA fragment coding for the full-length mature protein (residues Q16 to M142, variant H2) was amplified by PCR and subcloned into the pRBI-DsbC expression vector, as a fusion construct with the OmpA periplasmic signal sequence (oligonucleotides used for subcloning are given in Supplementary Table S2).
For the yeast two-hybrid screen a cDNA fragment coding for full-length human Mss4 (accession no.
In brief, a DNA fragment coding for mouse BCL-XL (residues 1 44 and 85 196) was cloned into pProEX-HTa (Invitrogen, Carlsbad, CA, USA).
For recombinant expression of the Cnidoin elastic domain a DNA fragment coding for amino acids GGQM-AGCG was amplified by PCR and cloned four times as a tandem repeat into the pet21 vector (Novagen, Whitehouse Station, New Jersey, USA).
To further narrow down the SLX4-binding region of MUS81, we subdivided this region and found that a MUS81 fragment coding for amino acids 1 106 is sufficient for interaction with SLX4 (Fig. 1A and B).
