S. Mentzel et al., CHARACTERIZATION OF A 43-KD PROTEIN ASSOCIATED TO AMINOPEPTIDASE-A FROM MURINE KIDNEY, Biological chemistry Hoppe-Seyler, 375(9), 1994, pp. 623-627
SDS-PAGE of affinity-purified APA under reducing conditions showed in
addition to the specific APA band of M(r) 130 kD, a second band of M(r
) 43 kD. Internal amino acid sequencing of three tryptic peptides from
this second band, that was cut out of the polyacrylamide gel, matched
the actin sequence. The identity of the 43 kD band was also confirmed
by Western blotting.
